AIM: How do scientists represent the evolutionary relationships between species?
Today we talked about extinction and looked at how scientists represent relationships through evolutionary trees.
Reading and interpreting relationships from an evolution tree:
Who descended from who? Who evolved from who? Who evolved into what? Which species are extinct? Where have species diverged? Who is a common ancestor? What is the earliest common ancestor? Which species are adapted to the present environment? Which species (if any) were unable to compete?
Be sure to look at the evolutionary trees from today’s PowerPoint and tonight’s homework.
Descend- to come from
Diverge- to split off
