...Keith Tognetti Abstract A stable population, such that the total birthrate B(t) = B o e r o t , is abruptly altered by modifying the age-specific birth rate, m(x) . The survivor function remains unaltered. The modified population ultimately settles down to a stable behavior, such that B(t) = B 1 e...

This effect on health at birth is a function of two countervailing mechanisms: (1) negative selection of less healthy embryos and fetuses not surviving (raising the average health of survivors...
