Transcript

00:01 Going right from the top for 1a, we have a matching section.

00:06 It starts with a derived form of a trait that's shared by a group of related species.

00:13 And this indeed would be a synapomorphy.

00:16 So we'll just write these down in the order of the blanks.

00:24 Next, we have the outgroup.

00:28 As an outgroup is a group of organisms that are closely related but are not direct, members of the group being studied.

00:36 And so oftentimes in cladistics, you'll have sort of, i'll just have this drawing in the side.

00:41 We'll have a little tree, perhaps, of organisms.

00:48 At each of the ends of the branches, they're being sort of an organism.

00:52 And this is sort of the group that's being studied.

00:55 We'll have an out group here, which is sort of the next closest related group of animals that is not within the group being studied.

01:02 And so this would be the out.

01:08 Third, we have.

01:09 Have an organism and all of its descendants that is a clade that's sort of the definition of the clade and finally um the point of divergence in which a a lineage splits um and that would be a node that's sort of another term used in cladistics quite commonly and so that is the answer to one a moving on to one b we have a multiple choice question here um that asks which of the following taxonomic group would have a species with similar phenotypes as a result of convergent evolution...
