Evolution Review 2023 Biology

Our best scientific evidence today suggests that

• modern humans evolved from chimpanzees

• humans and chimpanzee share a common ancestor

• the human species has stopped evolving

• chimpanzees evolved from humans

The first known life arose around

• 3.5 billion years ago

• 4.6 billion years ago

• 2 million years ago

• 100,000 years ago

A calcareous mound built up of layers of lime-secreting cyanobacteria and trapped sediment, found in Precambrian rocks as the earliest known fossils, and still being formed in lagoons in Australasia.

• amino acids

• heidelbergensis

• stromatolites

• trilobites

Among the pieces of evidence that all life on Earth shares common ancestry is the fact that- check all that apply

• all living organisms contain DNA

• all living things are made of many cells

• Embryology- embryos of many organisms look similar

• all cells contain a nucleus

The snake has a pelvic bone... This is an example of a

• Embryological structure

• Homologous structure

• Vestigial structure

• Biochemical structure

Natural selection always leads to an increase in a species’

• range

• geographic isolation

• gene pool

• fitness

Some argue that evolution is not true, because it is "just a theory". How might you respond to that? (Pick the best statement).

• They are correct because a theory is a lot like a hypothesis. More research needs to be done in order to add validity to the statement

• They are incorrect because a theory is a collection of facts that scientists have reviewed and acknowledged as true through studies, observations and peer reviews

• They are correct, because it is really just a hunch or idea.

• They are incorrect because a theory is a proven fact and can never be unproven.
