alleryThe strong similarity among the early embryos of different vertebrates is taken as evidence that these animals share a:
ASingle habitat
BCommon origin
CCommon diet
DSame lifespan
Answer & Solution
Correct answer: B. Common origin
1. Embryos of different vertebrates look extremely similar in early stages.
2. These similarities gradually decrease as development proceeds.
3. The early resemblance indicates the animals share a common origin.
4. A common diet or habitat is not implied by embryo similarity, so those are ruled out.
