I have this worksheet for science, but this isn't in my textbook. I have to match these events to a geologic timeline. The choices are:

A. modern humans evolve, B. first multicellular organisms, C. land plants evolved, D. dinosaurs flourished, E. mammals evolved, F. large mammals evolved, G. marine reptiles evolved, H. dinosaur extinction, I. first vertebrates evolved, J. first shelled invertebrates.

The periods are:
Precambrian (this one isn't listed under an era)

Eocambrian, Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, and Permian (under the Paleozoic era)

Triassic, Jurassic, and Cretaceous (under Mesozoic era)

And lastly, Tertiary and Quaternary (under Cenozoic era)



Those were all in order. Help me if you dare :]

Throw a spanner in the works and tell them that God created the world and evolution is only a theory that is actually hogwash.
