WebThis pattern repeats as one goes through the phylogenetic tree of life: A change in an organism’s genetic makeup leads to a new trait which becomes prevalent in the group. Many organisms descend from this point and have this trait. New variations continue to arise: some are adaptive and persist, leading to new traits.
