TEKS

7A Analyze and evaluate how evidence of common ancestry among groups is provided by the fossil record, biogeography, and homologies, including anatomical, molecular, and developmental

7BExamine scientific explanations of abrupt appearance and stasis in the fossil record

Open Ended

Based on what you heard in the video,what did they mean by Evolution?

Open Ended

Name one evidence for Evolution

Multiple Choice

Why are fossil records incomplete?

• Because the fossil record was altered by archeologists over time and therefore fossils went missing.

• Because, in prehistoric times, there were not a lot of early forms of life and therefore the ones that were there fossilized.

• because many early forms of life were soft-bodied. The soft parts of organisms do not form fossils well.

• Because the fossil record, has not fully been excavated, therefore archeologists don't know if its complete.

Based on the video, what were the paleontologists looking for?

Multiple Choice

Based on the previous slides, Why is Archaeopteryx known famously as a transitional fossil?

• All of the Above

• because the fossil gives evidence for the evolution of modern birds from dinosaurs.

• Because it looks like a raptor from the Cretaceous era.

• Because it became a hard part and was fosillzed and preserved.

Open Ended

Name one evidence that supports Evolution

Multiple Choice

What is punctuated equilibrium?

• Where species evolve slowly over time.

• the theory that drastic changes

  create new species that then change very little over time

• where species grow and develop and inhabit the area.

• Where species compete for limited resources and the strongest survive.

Multiple Choice

What is Gradualism?

• It is when species do not fossilize well and therefore there are gaps in the fossil record.

• It is when one species benefits from the relationship and other is harmed.

• It is when species do not evolve and there is little to no change in their appearance.

• the theory that species evolve gradually and

  consistently over time

based on the lesson, Why do you think we evolved from primitive species?
