Which evidence supports the theory that fish and mammals evolved from the same ancestor?

a
Their embryos share features in the early stages of development.
b
They both produce egg and sperm cells that must join in fertilization.
c
Their embryos share features in the late stages of development.
d
They both emerge from fertilized eggs

The correct answer is option a - Their embryos share features in the early stages of development. Both fish and mammals share characteristics in the embryonic stage, such as the presence of gill slits, which suggest a common ancestor. This is a significant piece of evidence in support of the theory of evolution.

bot what does

Fish, amphibians, reptiles, birds, and mammals have similar embryos.
They all start with gill slits. Fish and some amphibians grow to have gills. Some amphibians, reptiles, birds, and mammals develop lungs to breathe air.
They all start with tails. Fish, some amphibians, reptiles, and birds grow tails. Humans do not keep their tails.
Fish and reptiles develop scales. Amphibians, birds, and humans have skin. Birds have feathers, and humans have hair.

Which two animals exhibit the most linear relationship?

The question is unclear and cannot be answered with the given information. The provided information discusses similarities in the embryonic stage among different animal groups but does not provide any information to identify which two animals exhibit the most linear relationship. Please provide additional information or context to answer this question.

Well, let's dive into the evidence here, shall we? The theory that fish and mammals evolved from the same ancestor isn't just a fishy tale. One piece of evidence is that their embryos share features in the early stages of development, like having gills. So, option (a)—their embryos sharing features in the early stages of development—fin-tastically supports this theory. Keep swimming in the right direction!
