Two striking differences between humans and our closest living relatives, chimpanzees and gorillas, are the size of our brains (larger by a factor of three or four) and our life span (longer by a factor of about two). Our thesis is that these two distinctive features of humans are products of coevolutionary selection. The large human brain is an investment with initial costs and later rewards, which coevolved with increased energy allocations to survival. Not only does this theory help explain l ...[more]

Project description:The ageing of the European population is expected to strongly influence both the structure of family relations and the pattern of private transfers between generations. Using data from the Survey of Health, Ageing and Retirement in Europe conducted from the perspective of adults aged 50 and above in ten European countries, we provide an analysis of financial and time transfers, either given or received. Our results show that cash gifts mainly flow to the younger generations, while time transfers are directed both upwards and downwards. When comparing the countries, we find some remarkable similarity in the pattern of transfers, although there are inter-country differences. These differences sometimes follow the expected north-south European gradient, but not always. The results suggest that the social and demographic transformations currently taking place in Europe often have contradictory and paradoxical effects upon the nature of intergenerational exchanges.

Project description:Intergenerational private transfers should be made important as a common occurrence in familialistic societies when establishing the identity of Southern European welfare state regimes. They function as a safety net and as a way of reinforcing the bonds amongst elements in a family. Although Portugal is undoubtedly a Southern European country, it is frequently ignored in comparative studies, and is assumed to share the characteristics of Spain and Italy. But do these countries really belong to a common, distinctive model? Portugal was included in the fourth wave of the survey of health, ageing and retirement in Europe, which provides a large sample for the study of intergenerational private transfers in this country. It also enables comparison with what happens elsewhere in Europe. We examine the upward and downward flows between generations and identify several important determinants of each type of transfers. Additionally, we show that the different types and directions of transfers are positively correlated, pointing to a self-reinforcement of transfer behaviour in families. We find that Portugal has an especially low probability of private transfers of time and money. After taking into consideration the household-level characteristics, none of the countries included in this study has a significantly lower probability of occurrence of any type of transfer than that of Portugal. A Southern European specific pattern of family transfers is only partially confirmed, yet Portugal and Spain do share the same model.

Project description:We report the application of mRNA sequencing technology for identifying that the genetic linkage of higher intelligence with longevity in Drosophilla melanogaster. a transcriptome analysis was performed by sequencing the total mRNA. The differentially expressed gene analysis by a negative binomial test showed that a subset of genes displayed remarkably altered expression where 56, 152, and 26 genes were significantly upregulated (adjusted P value <0.01), and 30, 397, and 10 genes were downregulated (adjusted P value < 0.01) in INT compared to F0, NINT compared to F0, and INT compared to NINT each. The functions of the differentially expressed genes were analyzed at high levels by using Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment program. Compared to F0, the pathways of ribosome and autophagy were up-regulated in INT while the pathways related to metabolisms were down-regulated. Meanwhile, the pathways associated with genome stability and immune reaction was upregulated and the pathway of oxidative phosphorylation responsible for ATP generation was down regulated in NINT. The KEGG comparison of INT with NINT, which eliminates genes associated with the environmental factors during the selection process, visualized more precise pathways associated with higher intelligence and longevity. The pathways related to genome stability (Fanconi anemia pathway, Mismatch repair, DNA replication, Homologous recombination, and Nucleotide excision repair) and immune reaction (Toll and lmd signaling pathway) were up-regulated in NINT, and these pathways were down-regulated in INT.

Project description:BackgroundLack of nutrition, inadequate housing, low education and limited access to quality care can negatively affect children's health over their lifetime. Implemented in 2003, the Bolsa Familia ("Family Stipend") Program (PBF) is a conditional cash transfer program targeting poor households in Brazil. This study investigates the long-term benefits of cash transfers through intergenerational transmission of health and poverty by assessing the early life exposure of the mother to the PBF.MethodsWe used data from the 100M SINASC-SIM cohort compiled and managed by the Center for Data and Knowledge Integration for Health (CIDACS), containing information about participation in the PBF and socioeconomic and health indicators. We analyzed five measures of newborn health: low (less than 2,500 g) and very low (less than 1,500 g) birth weight, premature (less than 37 weeks of gestation) and very premature (less than 28 weeks of gestation) birth, and the presence of some type of malformation (according to ICD-10 codes). Furthermore, we measured the early life exposure to the PBF of the mother as PBF coverage in the previous decade in the city where the mother was born. We applied multilevel logistic regression models to assess the associations between birth outcomes and PBF exposures.ResultsResults showed that children born in a household where the mother received BF were less likely to have low birth weight (OR 0.93, CI; 0.92-0.94), very low birth weight (0.87, CI; 0.84-0.89), as well as to be born after 37 weeks of gestation (OR 0.98, CI; 0.97-0.99) or 28 weeks of gestation (OR 0.93, CI; 0.88-0.97). There were no significant associations between households where the mother received BF and congenital malformation. On average, the higher the early life exposure to the PBF of the mother, the lower was the prevalence of low birth weight, very low birth weight and congenital malformation of the newborn. No trend was noted for preterm birth.ConclusionThe PBF might have indirect intergenerational effects on children's health. These results provide important implications for policymakers who have to decide how to effectively allocate resources to improve child health.

Project description:The aim of this study is to determine the likelihood and net amount of parent-child transfers over the adult life cycle across European welfare regimes. The study introduces an economic life-cycle model of family transfers to describe the evolution of family exchanges across generations over time, which reveals a nonlinear relationship of age and net family transfers. Furthermore, it refines the method of estimating parent-child net transfers. Data come from the Survey of Health, Ageing, and Retirement in Europe, and include 36,095 parent-child dyads from 11 European countries representing social democratic, conservative, and traditional welfare-state regimes. The findings reveal net value of family intergenerational support follows a nonlinear pattern across the adult life cycle, with positive transfers from parents to adult children decreasing modestly until advanced old age when the decrease intensifies. Net family support benefits individuals and generations with larger relative need. The transition in the net family support pattern starts later and is less pronounced across social democratic welfare-regime countries while the opposite is true in traditional welfare-regime countries. These findings might be interpreted as being linked to differences in the public policies guaranteeing different levels of provision for dependent populations across different welfare regimes. They are consistent with a comparatively smaller role of family support in the intergenerational redistribution of resources in societies with larger public intergenerational support to dependent populations.

Project description:In birds and primates, the frequency of behavioural innovation has been shown to covary with absolute and relative brain size, leading to the suggestion that large brains allow animals to innovate, and/or that selection for innovativeness, together with social learning, may have driven brain enlargement. We examined the relationship between primate brain size and both technical (i.e. tool using) and non-technical innovation, deploying a combination of phylogenetically informed regression and exploratory causal graph analyses. Regression analyses revealed that absolute and relative brain size correlated positively with technical innovation, and exhibited consistently weaker, but still positive, relationships with non-technical innovation. These findings mirror similar results in birds. Our exploratory causal graph analyses suggested that technical innovation shares strong direct relationships with brain size, body size, social learning rate and social group size, whereas non-technical innovation did not exhibit a direct relationship with brain size. Nonetheless, non-technical innovation was linked to brain size indirectly via diet and life-history variables. Our findings support 'technical intelligence' hypotheses in linking technical innovation to encephalization in the restricted set of primate lineages where technical innovation has been reported. Our findings also provide support for a broad co-evolving complex of brain, behaviour, life-history, social and dietary variables, providing secondary support for social and ecological intelligence hypotheses. The ability to gain access to difficult-to-extract, but potentially nutrient-rich, resources through tool use may have conferred on some primates adaptive advantages, leading to selection for brain circuitry that underlies technical proficiency.

Project description:The aim of this study was to examine the net balance of transfers between persons aged 50 and older and their family, taking into account both the exchange of money and the exchange of practical assistance (time). Toward this end, a unique net balance outcome measure was computed by costing the value of time transfers into wage equivalents. The study made use of data from the first wave of the Survey of Health, Ageing and Retirement in Europe (SHARE), and focused upon intergenerational exchange in two specific countries: Germany and Israel. The descriptive findings show that-up to an age of about 80 years-the elderly are net providers of help. The outcome variable was next regressed on a set of relevant predictors identified in the literature on intergenerational transfers and support-among them, sociodemographic background, health, social policy, social network and motivation variables. Holding these variables constant, the balance pattern by age remains valid: respondents aged 50-79 in both settings contributed to their family more than they received. These trends in net transfer exchanges were largely similar across both countries and across regions or population groups within both countries. Women were more likely to have a positive net exchange balance and poorer health was associated with net receiving. However, differences also emerged: social capital was more clearly associated with a positive exchange balance in Israel, transfer motivations shaped transfer behaviors in Germany but not in Israel, and socioeconomic variables seemed to work in opposite directions in the two countries. In sum, the results underscore the generally positive contribution of older people to intergenerational exchange in the family. This outcome holds for both Germany and Israel despite their very different conditions of context.

Project description:Why do humans survive so long past reproductive age, and why does juvenile mortality decline after birth, both contrary to the classic theory of aging? Previous work has shown formally that intergenerational transfers can explain both these patterns. Here, simulations confirm those results under weaker assumptions and explore how different social arrangements shape life-history evolution. Simulated single-sex hunter-gatherers survive, forage, reproduce, and share food with kin and nonkin in ways guided by the ethnographic literature. Natural selection acts on probabilistically occurring deleterious mutations. Neither stable population age distributions nor homogeneous genetic lineages are assumed. When food is shared only within kin groups, an infant death permits reallocation of its unneeded food to the infant's kin, offsetting the fitness cost of the death and weakening the force of selection against infant mortality. Thus, evolved infant mortality is relatively high, more so in larger kin groups. Food sharing with nonkin reduces the costs to kin of child rearing, but also reduces the resources recaptured by kin after an infant death, so evolved infant mortality is lower. Postreproductive adults transfer food to descendants, enhancing their growth and survival, so postreproductive survival is selected. The force of selection for old-age survival depends in complicated ways on the food-sharing arrangements. Population-level food sharing with nonkin leads to the classic pattern of constant low mortality up to sexual maturity and no postreproductive survival.

Project description:Cooperative behaviours in archaic hunter-gatherers could have been maintained partly due to the gains from cooperation being shared with kin. However, the question arises as to how cooperation was maintained after early humans transitioned to larger groups of unrelated individuals. We hypothesize that after cooperation had evolved via benefits to kin, the consecutive evolution of cognition increased the returns from cooperating, to the point where benefits to self were sufficient for cooperation to remain stable when group size increased and relatedness decreased. We investigate the theoretical plausibility of this hypothesis, with both analytical modelling and simulations. We examine situations where cognition either (i) increases the benefits of cooperation, (ii) leads to synergistic benefits between cognitively enhanced cooperators, (iii) allows the exploitation of less intelligent partners, and (iv) the combination of these effects. We find that cooperation and cognition can coevolve-cooperation initially evolves, favouring enhanced cognition, which favours enhanced cooperation, and stabilizes cooperation against a drop in relatedness. These results suggest that enhanced cognition could have transformed the nature of cooperative dilemmas faced by early humans, thereby explaining the maintenance of cooperation between unrelated partners.

Project description:The evolution of complex organismal traits is obvious as a historical fact, but the underlying causes--including the role of natural selection--are contested. Gould argued that a random walk from a necessarily simple beginning would produce the appearance of increasing complexity over time. Others contend that selection, including coevolutionary arms races, can systematically push organisms toward more complex traits. Methodological challenges have largely precluded experimental tests of these hypotheses. Using the Avida platform for digital evolution, we show that coevolution of hosts and parasites greatly increases organismal complexity relative to that otherwise achieved. As parasites evolve to counter the rise of resistant hosts, parasite populations retain a genetic record of past coevolutionary states. As a consequence, hosts differentially escape by performing progressively more complex functions. We show that coevolution's unique feedback between host and parasite frequencies is a key process in the evolution of complexity. Strikingly, the hosts evolve genomes that are also more phenotypically evolvable, similar to the phenomenon of contingency loci observed in bacterial pathogens. Because coevolution is ubiquitous in nature, our results support a general model whereby antagonistic interactions and natural selection together favor both increased complexity and evolvability.
