How did climate affect the spread of early humans?
Overall, the hominin fossil record and the environmental record show that hominins evolved during an environmentally variable time. Higher variability occurred as changes in seasonality produced large-scale environmental fluctuations over periods that often lasted tens of thousands of years.
What was the climate like 10 000 years ago?
About 10,000 years ago, Earth was closest to the sun during summer and farthest during winter. Today it is the opposite. Based on this variable alone, we would expect winter warming and summer cooling in the northern hemisphere (and vice versa in the southern hemisphere) over the last 10,000 years.
How did climate affect the development of human cultures during the ice age?

Are humans teeth designed to eat meat?
