Question 1
1 Â
Which of the following statements represents evidence that supports the theory of common descent but specifically contradicts the hypothesis of separate types?
Answer:- Many genes found in humans are also found in yeast and they perform the same function in yeast that they do in humans.
The fossil record provides substantial evidence that humans and chimps share a common ancestor.
Radiometric dating methods show that Earth is billions of years old.
Many genes found in humans are also found in yeast and they perform the same function in yeast that they do in humans.
The fossil record provides copious unequivocal evidence that the species that inhabit Earth have changed dramatically over time.

Question 3
1 Â

The development of traits that organisms need in order to become more complex.
Gene changes in populations over many generations.
The change that occurs in individuals as they try to survive in their environment.
