Question

How did early humans adapt to the changing enviroment 

Answer 1

Early humans were the first homo sapiens to evolve with bipedal locomotion and sophisticated brain.

 

They performed certain tasks easily than their ancestral counterparts, such as making sophisticated tools and keeping themselves away from predation/injury by  their wild ancestors.

 

These human discovered fire and farming as response to harshness and scarcity of food in their environment.

 

At the same time, evolutionary forces retained their newly acquired genes that they could pass on  to their progeny. They took care of their  vulnerable infants and in fact imparted survival skills as well as linguistic communicative ability to their children thereby continuing to survive and thrive in wilderness as newly emerged species that was dtermined to survive and thrive in the wild world as a ruling species of animal kingdom.
