Create a list of 5 characteristics that make vertebrate and invertebrates different

differences similarities The notochord in vertabrates became a spine.
All at one time had a notochord.
Invertabrates have no spine, just a notochord which is a rod like body that is flexible and formed of cells derived from the mesoderm.
Both can reproduce
Some invertebrates have nothing supporting a structure and are completely gelatinous in shape.
Both are animals or in many …show more content…
1. Your text offers evidence of evolution including: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology. In your opinion, which of these provides the strongest evidence for evolution? Which provides the weakest argument for evolution?
Fossil records are etched in stone and prove that all life began somewhere and shows a timeline of the origin of new physical features. From fossil records you can gather when a species occurred, how they looked, what they ate, where they lived and many other forms of data which can not otherwise be gathered. I believe that this is the best way to provide evidence for evolution because it is basically documentation in stone and nothing beats documentation. The other methods which are biogeography, comparative anatomy, comparative embryology, and molecular biology can be considered as inferences or guess work.
