WebbUniversal common descent is a general descriptive theory concerning the genetic origins of living organisms (though not the ultimate origin of life). The theory specifically postulates that all of the earth's known biota are genealogically related, much in the same way that siblings or cousins are related to one another. WebbThese genes serve as a record that all life on Earth shares a common ancestor. Organisms that share a lot of traits generally have many more genes in common. For example, frogs and cows share the genes for making shared traits—like eyes, hearts, blood, bones, and nerve cells that look a certain way. css import html file
