The Amazing Cheesy Adventures of Professor Sandersons Paleobiology Class Part 1 TherapsidsI hope you guys have as much fun reading this as I did writing it. _***The Amazing Cheesy Adventures of Professor Sandersons Paleobiology Class probe 1 Where did mammals come from? Or Therapsids**Professor Sandersons class was popular. Partly this was because he was a well-meaning psyinstructor the images he crafted were neat, cohesive, and usually entertaining. Mainly, though, it was because he was a young potent teacher at an all-girls college, who had the fortune to resemble Jai from Queer Eye For the Straight Guy.

Todays attendance was especially high. It was a Field Trip day. The term wasnt l iteral. There was no trip involved---simply the students closing their eyes and falling into the trance-like state from which the prof led their excursions. There, in the collective canvass of their psyches, he would build that days lesson, sculpting visceral images from his expansive knowledge of biology and his even more expansive creativity.Todays lesson was mammalian origins.Where do we come from? he had asked, by way of preamble. We all know the basic answer, or think we do. Apes, right? And apes from primates, and primates from mammals, all well and good. But where do mammals come from? I mean, what did mammals evolve from, and what were the major evolutionary steps they took to get there? Doesnt that sound fascinating? The class eyed him warily. A few in reality listened.

The main thing were going to see directly is a group of animals called the therapsids.
