If Hutton’s or Lyell’s principle of gradualism (the concept that Earth’s geologic features were formed gradually) is applied to biological change, what logical inference would Darwin draw?

Prokaryotes (like bacteria) often evolve faster than humans primarily because:

A bat’s wing and a butterfly’s wing both allow for flight, but they evolved from different ancestral structures. These two structures are an example of:

The concept of descent with modification would predict that two organisms that share a more recent common ancestor (closer fork on the tree) are more likely to share:

A scientist observes that a specific gene is involved in regulating cell division and is almost identical in yeast, fruit flies, and humans. This is best described as an example of:

A population of finches has a wide distribution of beak sizes. During a severe drought, only large, hard seeds are available. Birds with small beaks die, while birds with large beaks survive and reproduce. This is an example of:

In the Tristan da Cunha example, one of the 15 founders carried a recessive allele for retinitis pigmentosa. The frequency of this allele in the island population is much higher than in the original British population. This demonstrates that:
