common ancestry and structures\nnew species evolve from a common ancestor. we show this evolution in an evolutionary tree. over time, we look and compare different kinds of structures. vestigial structures are structures that once had a purpose but are no longer needed. homologous structures are structures that are related and shared between species. analogous structures serve the same function but are not the same.\ndarwin stated that all species have descended from other species with modifications over time. what does this mean?\nmost life started out in the oceans.\nplants and animals have co - evolved.\nall life shares a common ancestor.
