I recently read a theory that states that the older the paternal Haplogroup the less chances to produce children. The two main reason where:
1 - low sperm count for males.
2 - females could only conceive if they had an orgasm in the very very old past.
The paper centred on the Australian Aboriginal , a K marker which has been in Australia for over 40000 years, yet when the whiteman arrived in 1780s there was only 3 million aboriginals.
Paper also stated that females in time, mutated sexually to a form to be impregnated without achieving orgasm and later/younger paternal haplogroups produced more healthier sperm. This led to younger markers having a higher percentage of the populace.
Theory is if this original breeding "system" did not change/mutate over time, the worlds population would only be around 1 billion.
my question is how can after 40000 years, there be only 3 million aborignals in a land which was free of diseases in a land of plenty.?
any links on this topic would be appreciated
EDIT: max population was 1.2 million over 52000 years
