Re: Turakian Age: Drakine Population Dynamics
The breasts could be truely functional, a status symbol, a sexual symbol. Many animals have "decorations" to attract mates. It's possible that female draks have breasts just because the are pleasant to have.
We should also keep in mind that the word "most" really only means over 51%. 51% might die in child birth, and of the remainder 51% choose not to have a second child. It also means that at least 51% only have one child at a time and not twins.
A population of 1,000,000 females would indicate a minimum of 501,000 die in childbirth, and of the 499,000 remaining 250,000 choose not not have a second child. So 1,000,000 are born and 501,000 die. Their population is actually increasing at a slow rate, assuming wars and such are not to hard on the population growth.
