Which of the following provides the best example of how comparative embryology supports the theory of evolution?
Humans do not lay eggs as birds do, but birds produce yolk sacs instead of embryos, suggesting birds evolved later than humans.
Humans have a tailbone that is visible during embryonic development, which suggests that humans evolved to depend on a useful tailbone.
Humans do not have gills as fish do, but human embryos have gill slits, suggesting humans and fish share a common evolutionary ancestor.
Humans have stem cells that develop in an unpredictable way, which suggests that other organisms also evolved to develop in the same manner.
