An Introduction to Zoology - Friday, 1st Period
Cutter had briefly considered what would happen if he didn’t turn up to his class for the third week in a row, even though really one of those week’s they’d been on vacation so he felt that didn’t really count but in the end he had finally prepared a class and was ready Friday morning to give his lecture. At least preparing for class gave something to focus on and not feel so nervous about his date with Connor.
“This week we’re going to be begin covering animal evolution,” he began that week’s lecture and handed around the usual stack of notes that he’d made for the class, “animals first appeared in the Ediacarian Period, which was roughly 635 million to 541 million years ago and these were soft bodied forms that left traces of their bodies in shallow water sediments,”
“Most of the animals in the Ediacarian period were thin and their cells were capable of diffusing nutrients from the water,” he continued, “the first mass extinction event ended the Ediacarian and this in turn led to the Cambrian Period, which set off the great evolutionary radiation to lead towards creating the very first group animals or phyla,”
“Evolution also occurred very quickly in this time period, in the Cambrian Period we have our first known appearance of sponges. A few more examples of evolution include after the Permian Extinction where a group of sea anemones evolved a skeleton and then diversified into modern corals,”
“Anthropods have been the most diversity phyla since the Cambrian, Myriapods diversified into insects during the Devonian period,”
“The fossil record can be particularly useful to us when studying these evolutionary patterns, this is the history of life from fossils, the remains or imprints of organisms preserved in sedimentary rock, it is important for describing the progressive changes within an animal group and the evolution of that group,”
“For next week, I’d like you to prepare a report of an animal or insect of your choosing from one of these time periods and talk about how their evolution progressed,”
