Question

comparative embryology. check all that apply

explores how the embryo develops
illustrates the lack of a human tail during development
discusses how vertebrates develop similarly
explains how animals have a common ancestor
shows that missing gill slits in salamanders during development
supports in theory of evolution

Answer 1

Comparative embryology involves the study of embryos from different species to understand developmental processes and evolutionary relationships. Here are the applicable statements regarding comparative embryology:

1. **explores how the embryo develops** - **True**
2. **illustrates the lack of a human tail during development** - **True** (humans exhibit a tail in early embryonic stages, which regresses)
3. **discusses how vertebrates develop similarly** - **True** (many vertebrates have similar embryonic stages)
4. **explains how animals have a common ancestor** - **True** (similarities in embryonic development suggest common ancestry)
5. **shows that missing gill slits in salamanders during development** - **False** (salamanders do have structures that resemble gill slits in their embryonic development)
6. **supports the theory of evolution** - **True** (provides evidence for evolutionary relationships and descent with modification)

Therefore, the statements that apply are 1, 2, 3, 4, and 6.
