Gène FTO et obésité

FTO genotype and weight loss: systematic review and meta-analysis of 9563 individual participant data from eight randomised controlled trials
http://www.bmj.com/content/354/bmj.i4707

Results We identified eight eligible randomised controlled trials for the systematic review and meta-analysis (n=9563). Overall, differential changes in body mass index, body weight, and waist circumference in response to weight loss intervention were not significantly different between FTO genotypes. Sensitivity analyses indicated that differential changes in body mass index, body weight, and waist circumference by FTO genotype did not differ by intervention type, intervention length, ethnicity, sample size, sex, and baseline body mass index and age category.

Conclusions We have observed that carriage of the FTO minor allele was not associated with differential change in adiposity after weight loss interventions. These findings show that individuals carrying the minor allele respond equally well to dietary, physical activity, or drug based weight loss interventions and thus genetic predisposition to obesity associated with the FTO minor allele can be at least partly counteracted through such interventions.

Left Liberals shy away from "actual IQ science" because the idea that people inherently differ in an aptitude that predicts crime, earnings and lifespan and is largely genetic is totally repugnant to them and undermines their views on how to make the world a better place.

"People with higher IQs are much more likely to become innovators"


The Social Origins and IQ of Inventors
Philippe Aghion, Ufuk Akcigit, Ari Hyytinen, Otto Toivanen
February 4, 2018
https://static1.squarespace.com/static/ … ht_fin.pdf

In this paper we merge three datasets - individual income data, patenting data,
and IQ data - to analyze the determinants of an individual’s probability of invent-
ing.  We  find  that:  (i)  parental  income  is  positively  associated  with  the  probability
of inventing, yet the estimated impact of parental income is greatly diminished once
parental socioeconomic status, parental education, and the individual’s IQ are con-
trolled  for;  (ii)  IQ  has  both  a  direct  effect  on  the  probability  of  inventing  and  an
indirect impact through education; the impact of IQ is robust to controlling for un-
observed family characteristics by focusing on potential inventors with brothers close
in age; and the effect of IQ is larger for inventors than for medical doctors or lawyers;
(iii) social family interactions also matter,  as shown by looking at biological versus
non-biological  parents;  (iv)  there  is  a  positive  and  significant  interaction  effect  be-
tween IQ and father income.

How long does it take to become a proficient hunter? Implications for the evolution of extended development and long life span
Michael Gurven, Hillard Kaplan, Maguin Gutierrez
https://www.sciencedirect.com/science/a … 8406000960

Human hunting is arguably one of the most difficult activities common to foraging peoples now and in the past. Children and teenagers have usually been described as incompetent hunters in ethnographies of hunter-gatherers. This paper explores the extent to which adult-level competence is limited more by the constraints of physical capital, or body size, and brain-based capital, or skills and learning. The grandmother hypothesis requires that production is an increasing function of size alone, while the embodied capital model stipulates that production is a function of both size and delayed learning. Tests based on observational, interview, and experimental data collected among Tsimane Amerindians of the Bolivian Amazon suggest that size alone cannot explain the long delay until peak hunting productivity. Indirect encounters (e.g., smells, sounds, tracks, and scat) and shooting of stationary targets are two components of hunting ability limited primarily by physical size alone, but the more difficult components of hunting—direct encounters with important prey items and successful capture—require substantial skill. Those skills can take an additional ten to twenty years to develop after achieving adult body size.

How to explain the unusually late age at skill competence among humans
Caroline Schuppli, Karin Isler, Carel P. van Schaik
https://www.sciencedirect.com/science/a … 8412001777

Humans stand out among primates and other mammals in reaching adult-level foraging skills very late in development, well after the onset of reproduction. The aim of this paper is to place this unusual human skill development into a broader comparative context. Among birds and mammals in general, duration of immaturity, indexed by age at first reproduction (AFR), and adult brain size have undergone correlated evolution. This pattern is consistent with two causal processes: AFR is either limited by the time needed to learn adult-level skills (needing to learn) or by the energy needed to grow brain and body to full size (energetic constraints). We tested predictions arising from these two hypotheses with data retrieved from the published literature for 57 mammal and bird species. First, most mammals reach adult-level foraging skills well before the developmental period is completed, implying that energy constraints determine the age at first reproduction, whereas most birds reach adult-level foraging skills around the time of maturity, suggesting time needed for skill acquisition determines the onset of reproduction. Second, within mammals we found that with increasing niche complexity, the age of adult-level skill competence moves closer to the age at first reproduction. Third, when looking at how adult-level skills can be reached later, we found that gregariousness, slow conservative development and post-weaning provisioning allow mammals to reach their skills later. Finally, in species with intense sharing of resources (such as cooperative hunters) competence in foraging skills may even reach peak values after age of first reproduction. We conclude that the human pattern of skill acquisition could arise because our hominin ancestors added cooperative breeding and hunting to the slow development they had as great apes with increasingly complex niches. This result provides a broad biological foundation for the embodied capital model.

Life history, cognition and the evolution of complex foraging niches
Caroline Schuppli, Sereina M.Graber, Karin Isler, Carel P. van Schaik
https://www.sciencedirect.com/science/a … 841500278X

Animal species that live in complex foraging niches have, in general, improved access to energy-rich and seasonally stable food sources. Because human food procurement is uniquely complex, we ask here which conditions may have allowed species to evolve into such complex foraging niches, and also how niche complexity is related to relative brain size. To do so, we divided niche complexity into a knowledge-learning and a motor-learning dimension. Using a sample of 78 primate and 65 carnivoran species, we found that two life-history features are consistently correlated with complex niches: slow, conservative development or provisioning of offspring over extended periods of time. Both act to buffer low energy yields during periods of learning, and may thus act as limiting factors for the evolution of complex niches. Our results further showed that the knowledge and motor dimensions of niche complexity were correlated with pace of development in primates only, and with the length of provisioning in only carnivorans. Accordingly, in primates, but not carnivorans, living in a complex foraging niche requires enhanced cognitive abilities, i.e., a large brain. The patterns in these two groups of mammals show that selection favors evolution into complex niches (in either the knowledge or motor dimension) in species that either develop more slowly or provision their young for an extended period of time. These findings help to explain how humans constructed by far the most complex niche: our ancestors managed to combine slow development (as in other primates) with systematic provisioning of immatures and even adults (as in carnivorans). This study also provides strong support for the importance of ecological factors in brain size evolution.
