    All of us are related on this planet…. we all carry DNA. It is just in different order on the genes and chromosomes.

    The closer an animal is to humans, the nearer were our common ancestors. We study and dissect fetal pigs because the are very close to human anatomy. And all chordates (animals with a spinal chord) are all built on the same pattern… head, body, tail, and four limbs……….all of us. (yes, you have a tail).

    So by studying other animals, you learn how humans work. It’s called "comparative anatomy".
