A: erectus is the most recent ancestor to modern humans.
Q: Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects?
A: The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.
Q: Human embryos have tails, which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals. Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate?
