In this example, we're exploring a question that asks us about which of the protostome phyla is distinguished as having body segments that are organized into what we call tagma or tagmata.
00:18
That's just a singular and plural of the word.
00:22
So the first thing we want to do is give ourselves some images.
00:25
When you're answering a question like this, the first and best thing to do is to identify what your phyla are, right? so this is a representative example of the analysts.
00:34
You might think of them as worms.
00:38
We also have a representative example here of the mollusks, which some of you might think of as clams, anything that has a shell.
00:47
We've got a snail here as an example.
00:50
And then, of course, we have the arthropoda or the arthropods, which is arguably the most diverse phyla in the animal kingdom, having all of the insects included in that particular phyla.
01:04
So now we know which phylo we're looking at.
01:07
So within the protostomes, we're thinking of it's either the analids or the mollusks or the arthropods.
01:12
Next, we need to define this other term that's been introduced in the question, and that's the togma or the togmata...
