Which traits do human embryos have that link them to a common ancestor with fish and reptiles? a. scales and tail b. gill slits and scales c. tail and gill slits d. hair and tail

Hi!

The correct option would be C.

Explanation:

Embryos of various species are observed to be similar during the early stages of development. This is due to the species having a common ancestor at some point. Human embryos have certain characteristics that indicate that it's ancestor has been one shared with fish and reptiles. Gill slits are present in both human and fish embryos, and is seen to develop into gills in fish, but disappears in humans before birth. Human embryos and reptile embryos are both seen to exhibit the structure that gives rise to a tail in reptiles, but in humans it does not develop the length and is seen as a tailbone at the end of the spinal cord.

Hope this helps!
