Document Summary
They are more closely related to animals then they are to plants. They have multiple flagella that push water which can make them move. Choanoflaggelate (protest) they are almost like cells, they are unicellular and are possible of attaching to each other and forming small colonies. They have multiple cnidocyte which care small barbs that attach to they use to attach to prey to keep them from moving. ~3. 8 billion years but animals didn"t show up until ~600 million years ago. The period where we first start to see some multicellular organisms is called the ediacaran period; there are almost no animal fossils from this time period. When the cambrian period comes along tons of fossils that are close to the phyla that we have today. Know classification (different classes and hoe they relate to each other, based off of the lecture material). Understand how the common ancestors work and what is more related to what, most closely related ancestor.
