Hello,
I ask for suggested reading / links on this subject:
What length of generation is used for calculating from
early man on? Sorry if I ask trivia, but I don't find anything
useful with google.
Is it something like "Lucy- type
female gave first birth aged 12, and fertility coming later
together with longer lifespan, longer fertility
till 40000 years ago, and and than something
completely different happened." ??
(unfounded guesswork just to say what I want to know about)
Thanks,
ed wolf |

25 years is a good estimate |

Hello ,
isnīt that a rather long generation for the early years,
3.2 million years back? I thought Lucy (with maybe
25 years as I read) could have been a grandmother.
Where can I read more about it?
