A tetrapod is a(n) ____.

Fish are the earliest vertebrates.

Pollen morphologies change in response to atmospheric pollution and UVB radiation.

Cooksonia is the earliest known vascular land plant.

Animals lived on land before plants moved to land.

Explain how palynology can be used to reconstruct past environments.

In ____________________, a species produces two types of spores, one for the female gamete plant and one for the male gamete plant.

Seedless vascular plants release spores to the environment.

____________________ is the study of organic microfossils,

Explain why the development of the amniote egg was so significant in the evolution of the reptiles.

Based on embryo studies, blood proteins, and biochemistry of muscle activity, chordates may be more closely linked to echinoderms than other phyla.

Plants adapted to the desiccating effects of the land environment and increased ultraviolet radiation with the evolution of ____.

Compare and contrast the jawless and jawed fish. How do scientists think the jaw first evolved in fishes? Was the evolution of the jaw related to feeding?

Both sphenopsids and lycopsids were important members of the Pennsylvanian forests.

Gymnosperms represent the earliest flowering plants.

The Devonian period is also known as the "Age of Fish."

A(n) ____________________ is an animal that has, at least during part of its life cycle, a notochord, a dorsal hollow nerve cord, and pharyngeal slits.

A flowerless, seed-bearing plant is called a(n) ____.

Discuss how the evolution of jawed fishes and other predatory creatures affected the marine ecosystem.

Discuss the development of marine plants to primitive land-based plants to vascular plants to sphenopsids to gymnosperms. What changes in plant structures were required to make this transition?
