humans have a higher survival curve than chimpanzees aging is a complex trait: genes X environment having a sibling living to 100 increases your chances of living to 100 by 5-10 times amount hunger gatherers: 40-60% of adults are over 40 years old even as they age, they are still every active, daily walking is a lot until age 50, than decreases slowly until age 80 long lives are ancient: not only due to modern medicine hominins have been living into old age for at least 100000 years, less neanderthals living from 20-40 years old than modern humans more neanderthals living for >40 years old than modern humans Humans: long post-reproductive life for women, menopause, chimp females don’t have long life span after motherhood, medicine helps human women get to their potential old age to extend post-reproductive lifespan, natural selection: costly for grandma to care for children, but doesn’t have time to maintain herself, but can extend her genetics and pass on her genes, increase mother’s ability to reproduction, shares 2^x with descendants inclusive and indirect fitness = explains grandma hypothesis, explains sharing and slow life, altruisticact, glue is inclusive fitness, about your own fitness and keeping yourself alive and doing costly things that will benefit your kin humans life history differs from other apes: longer childhood, later age at maturity, faster reproduction, shorter inter birth interval, longer lifespan humans have more children in comparison to their size grandma’s have a lot of ability to care for grandchildren, time, wisdom, and experience, valuable for children learn to forage and socialize humans escape the life history trade-offs faced by other mammals, humans have the biggest brain size and birth per year, and day range (walking distance) and lifespan Humans = the high energy ape, we use the highest total energy expenditure, we have the highest basal metabolic rate (energy to keep us alive), we have a large energy budget well above BMR: provides more energy for reproduction and maintenance and big brains, can decide how to spend the energy humans have the largest fat mass, reserve of energy for high reproductive rate and maintain large brain even a lean person like Hadza have a high comparative body fat to pan, gorilla, and pongo food sharing and fat makes increased energy possible primate energy expenditure and link to life history leading sources of mortality in the US cardiovascular disease diabetes (type II) comparison of chronic disease in the US vs. Hunter-gatherers mismatch hypothesis highest leading causes of death: heart disease, cancer, chronic lower respiratory disease, stroke (cardiovascular disease), accidents, alzheimer’s disease, diabetes, nephritis, nephrotic syndrome, nephrosis
