Science 7 B - Comparing Vertebrate Embryos quick check answers

Answer 1

1. What is one similarity between the embryos of different vertebrate species?

One similarity between the embryos of different vertebrate species is the presence of gill slits in the early stages of development.

2. How do the development of vertebrate embryos provide evidence for evolution?

The development of vertebrate embryos provide evidence for evolution by showing similarities in the early stages of development, such as the presence of gill slits and tails, which suggest a common ancestry among vertebrates. This supports the idea of evolution from a common ancestor.

3. Why might differences in the embryos of different vertebrate species exist?

Differences in the embryos of different vertebrate species may exist due to adaptations to their specific environments and lifestyles. Evolutionary pressures may have led to modifications in the development of embryos to better suit the needs of the individual species.
