Images of the embryo and adult stages of three different organisms are shown.

Which of the following is the best conclusion that can be drawn from this evidence?

• Having similar embryos indicates that these organisms eat the same types of food.

• Having similar embryos indicates that these organisms share a recent common ancestor.

• Having similar embryos indicates that these organisms live in a similar environment.

• Having similar embryos indicates that a certain protein controls how many legs the adult organisms will have.
