Structures with the same parts have different functions; suggests that organisms share a common ancestry

vestigial structures

homologous structures

adaptive radiation

fossil

A category of structures that have a similar function, but are structurally different.

Homologous structures

Analogous structures

Vestigial structures

Common core structures

Why are advantageous traits more likely to be passed onto offspring?

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

Because the trait is an acquired phenotype.

Study of embryos of various organisms to show a common ancestor because of similarities in development

natural selection

embryology

speciation

evolution

A fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?

This is purely by chance and isn't significant

The extinct dinosaur and modern bird share a common ancestor

All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today

Dinosaurs choose to fly, and evolved into birds to escape predation and capture food

Which of the following organisms the kingdom animalia are not closely related?

mouse and hagfish

mouse and lizard

mouse and pigeon

mouse and chimp

Two organisms that are closely related would have

very similar DNA sequence

exactly the same DNA sequences

no proteins in common

completely different DNA sequence

Which of the following are examples of evidence for evolution?

Fossils and Cellular Structure

Biological Structures

Genetics/DNA

All of the Above

What are fossils?

Are the remains or evidence of once-living organisms

Is the change over time in populations of related organisms

A chart that divides Earth’s history into different time units

Occurs when the last individual organism of a species dies

10.

What is the fossil record?

Are the remains or evidence of once-living organisms

Is the change over time in populations of related organisms

Is made up of all the fossils ever discovered on Earth

Occurs when the last individual organism of a species dies

11.

In the model are rock strata and fossils. The fish fossil is in the first layer of the rock strata, is this the youngest or oldest fossil in these rock strata layers?

Youngest

Oldest

12.

Scientists theorize that the ancient horse on the left is related to the modern horse on the right. The scientists theorize that the horse has gone through many changes over time. How did the scientists conclude that the animal changed over time?

by examining fossil records

by learning about natural selection

by studying deposition of sediments

by observing different types of rock formations

13.

vestigial structures

analogous structures

homologous structures

fossil structures
