But it's broadly accepted though And it seems that the big jumps in brain size occurred at times when the Earth's orbit was most elliptical So the Earth's orbit oscillates It becomes more elliptical and more circular And there are many different oscillations driven by gravitational interaction with the planets like Jupiter in particular And it seems like when the Earth's orbit is most elliptical that the rate of climate change in the Rift Valley is higher and more extreme And it seems to be the case that there's relatively strong evidence for the case that when you get these really rapid times of climate change as you mentioned then you get increases in hominin brain size and therefore increases in intelligence @ https://youtu.be/Nt3jLx5eu4Q?si=1UKtmrOu56zKkK-x
