If two organisms show greater similarity, what can be inferred about their evolutionary relationship?
Answer and explanation
Correct answer: They may have a relatively closer evolutionary relationship
In evolutionary biology, shared structural, developmental or molecular features can indicate common ancestry. When two organisms show more significant similarities, they may have diverged from a relatively recent common ancestor and therefore have a closer evolutionary relationship. However, one superficial feature is not enough; several lines of evidence should be compared. Option A is correct. The other options wrongly deny relationships, equate species, or deny the presence of genes.
