Science 7 B - Understanding Human Evolution quick check answers

Answer 1

1. What is the theory of evolution?

The theory of evolution is the scientific explanation for how species have changed over time and how new species have emerged, driven by a process of natural selection.

2. What evidence supports the theory of human evolution?

Evidence for human evolution includes fossils of ancient human ancestors, comparative anatomy and physiology with other primates, genetic similarities between humans and other primates, and the study of embryos and vestigial structures.

3. How did bipedalism influence human evolution?

Bipedalism, or the ability to walk on two legs, influenced human evolution by freeing up the hands for tool use, changing the shape of the pelvis for more efficient walking, and allowing for greater energy efficiency when traveling long distances.

4. How does the fossil record contribute to our understanding of human evolution?

The fossil record provides physical evidence of human ancestors and their evolutionary changes over time, helping us to reconstruct the history of human evolution and understand how our species has developed and diversified.
