Understanding human evolution, quick check, answers

Answer 1

1. How have humans evolved over time?
- Humans have evolved physically, mentally, and socially over time, developing larger brains, upright walking, and complex societies.

2. What was the main factor driving human evolution?
- The main factor driving human evolution was natural selection, where individuals with advantageous traits were more likely to survive and reproduce, passing on those traits to future generations.

3. What are some key milestones in human evolution?
- Some key milestones in human evolution include the development of bipedalism (walking on two legs), the evolution of larger brains, the use of tools, the development of language, and the emergence of complex social structures.

4. How do genetic mutations play a role in human evolution?
- Genetic mutations can introduce new traits or variations in a population, which can be selected for or against depending on the environment. Over time, beneficial mutations can become more common in a population, leading to evolutionary changes.

5. Why is the study of human evolution important?
- The study of human evolution helps us understand where we come from, how we have adapted to our environment, and why we are the way we are today. It also sheds light on our place in the natural world and helps us better understand our connections to other species.
