Question

2. Humans, just like all other living organisms, have evolved over time. Explain how scientists

have measured this change by answering 2 of the 3 following questions
a. How do fossils of archaic humans show we have evolved?
b. About how similar is our DNA to chimps and how similar to an apple? What does that
mean?
c. Which species are our closest living relatives on the planet?

Answer 1

A. fossils of archaic humans show we have evolved through the differences in bone structure. Humans used to look a lot like chimps, and through fossils we can see differences in our skull shape and size, differences in the amount of body hair we had, and through vestigial bones like wisdom teeth, which we do not need anymore today. Wisdom teeth were likely used to chew raw meat, which we do not do anymore.

C. Chimpanzees are our closest living relatives on the planet, with 99% of our DNA being the same.
