Climate change has greatly affected how humans and our ancestors evolved. It created tough environments that made it harder to find food and survive.

Difficulties faced:

• Loss of places to live
• Fewer types of plants and animals
• More competition for food and resources

These problems helped shape how early humans looked and acted.

Potential solutions:

• Looking at fossil records (old remains of living things)
• Studying genetic traits (inherited characteristics)
• Using technology to understand ancient environments

By studying these things, we can learn how early humans were able to adapt and survive.
