Graph is on uncertain futures
1 is juvenile period/genetic info received

2 is growth and development/ptential environmental change

3+4 is adult and reproduction

key point organism spends time in 2 before it knows exactly what adult environment it will face
Longer developmental time → greater potential environmental change → more selection for ability to respond developmentally

Effects of childhood stress in age of:

measure of fecundity and fertility
early harvest and planting have higher chances of no ovulation and pregnancy loss due to intense labour
rainfall indirectly influences through nutrition and labour

Hazard ratios for CHD
ponderal index X axis = measure of body condition
BMI Y at 11 axis
low ponderal + low BMI at 11 = low risk

low + high = high risk

presence of post reproductive mother present at 1st reproduction

increased lifetime fecundity of offspring

increased lifetime reproductive success

through grandmoter hypothesis

Knowledge economy/tracking efficiency by ache men

peaks at age 38

wood preindustrial demography model
innovations increased population from point A which is the original resource per person
pop move to point B same resource per person
better technology does not equal better wellbeing
