The question is that we're supposed to look at a file, a genetic tree and look at specifically the 10 groups of Bilateral and we're to label each of them as having asylum, having a humus hill only if we're to look at and say, Okay, they have a human steel and a reduce Ealham, or if in fact, that there is nobody county whatsoever. So the first thing is to define some of these things so defining the seal, Um, we're going to define it as the body cavity and that its position to surround the digestive tract, and it contains the digestive tract and the organs, and it has fluid in it. And then the humus ill itself is primarily a body cavity, but it is usually found in vertebrates, and it typically contains a circulatory fluid known as him a limp. And it is in this human lymph where there is, um, between that and some of the other organs where there is an exchange of materials. Okay, So the first step was to go down the list of the 10 of bilateral and to put onto the file a genetic tree labeling whether they have no body cavity, as in a Seela and Plati hell mentees. Or if they have a pseudo Salem, which would be then some sort of, ah, modified or reduce Salem and a hey Maciel. And that would be routed Fra and Nima Tota. And then I would say that once that have seal, um but then also have Hamas ill would be, um, Alaska Arthur Pota And with arthropod, of course, there's the insects and crustaceans and then those that have Silom Onley And no, he Maciel would be heavy core data economy armada core data on an Elita with analysts. They have a close circulatory system, which is a lot like our own, our very own circulatory system. So since they have a close circulatory system, they do not have that humans feel. Typically, most organisms that we're gonna have a human cell are gonna have open circulatory systems because they've gotta have the circulatory fluid surrounding the organs. In addition to labeling whether the organisms have asylum or if they have only or if they have Mahama sell only or if it is a kind of a mixture between the famous seal and having reduced or smaller just not nearly quiet as involved as a whole entire seal, Um, or having absolutely no body cavity. There is also two questions to answer one of the questions, it says. Out of the three major plate, one of the plates that could be found on the diagram is due Tourist Home. The second and the third is the My Folks Truck Gaza and Appetizers Zola Looking at where these three plates sit on the entire of the pilot genetic tree, we find that the due to Estonia, all of the groups that air the due to stones have asylum. And so very likely the common ancestor for the Dura Stone is going toe. Have the seal, Um, And then when we look at the common ancestor between the life of Protozoa and the dice Isoa, what we find is that there is actually a mix. There's a mix of having that truce Eelam, And then there's other ones that are in the grouping that have more of what they call a pseudo seal, Um, or where there is more of a human seal and some some what pocketing of the seal? Um, it's not a true ceiling, but it z somewhat there is, ah, body cabinet, at least present. And then, uh, some of those that are involved in the groupings that don't even have the body cavity to build a have fluid in. And so the common ancestor is very likely to on those two, very likely to have started with no body cavity whatsoever and has a presence of Salem in the animals changed over the course of the evolution over the history that's involved. So we have at one point where there's not any body cavity and the more simpler animals that just simply is not a body cavity. And we go then Thio, where it's more of like a studio cilla mate. There's, um, out pockets. But it's not a true in fact entire seal them. And at the very end of that extreme is very much like what the do tourist OEMs have. And that is the true seal. Um, it's and it's indicated in the diagram as I've been answering the question. So the first question Waas to label the second question was analyzing the common ancestor between the shooter stones and then also between the little Fat Rocca's oh and the Giza. So, uh, and then the last part is what would be the sort of trend or what would be the way that we would see the evolution so would go from not having to having a variety of mixture. And this is especially with into in terms of the two claims over much later, um, in an earlier development and due to Estonia didn't pop out until much sooner in our evolutionary time period.
