Evidence for Evolution

Question 1

What is genomics?

Answer 1

The study of DNA base sequences and gene function

Question 2

How does the study of genomics provide evidence for evolution?

Answer 2

1. Genomics show that closely related species have more similar DNA because less time has passed for changes in the DNA sequence to occur
2. This shows that they have diverged more recently

Question 3

What is proteomics?

Answer 3

The study of proteins

Question 4

How does the study of proteins provide evidence for evolution?

Answer 4

1. Proteomics states that closely related organisms have similar DNA sequences and therefore similar amino acids sequences
2. This suggests that the organisms have diverged more recently because less time has passed fro changes to occur

Question 5

What does the theory of evolution suggest?

Answer 5

All organisms have evolved from a shared common ancestor and so there should be some similarities in every organism’s DNA sequence

Question 6

How is evidence for evolution and other discoveries validates?

Answer 6

1. Scientific journals
2. Peer review
3. Conferences
