Evidence of Evolution

Evidence of Evolution

By Erica Putnam

Multiple Choice

Which of the following is the collection of life's remains found in sedimentary rock?

• natural selection

• homologous structures

• Charles Darwin

• the fossil record

Multiple Choice

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show how life forms present today are different than those from the past
• Different sedimentary rock layers provide evidence for how the environment has changed over time

Multiple Choice

Which layer is the youngest

• 1
• 2
• 3
• 4

Multiple Choice

Which is the relatively youngest fossil?

• gastropod

• trilobite

• coral

• ammonite

Multiple Choice

What is the age of the shell fossils in the yellow layer?

• Between 495-510 mya

• Between 510-520 mya

• Between 520-545 mya

Multiple Choice

If two organisms have similar DNA they probably

• share a common ancestor
• share a common environment
• share a common population
• speciation

Multiple Select

Which two biochemical molecules can be used to determine evolutionary relationships?

• Carbohydrates

• Proteins

• DNA

• Lipids

Multiple Choice

Recently, scientists have been able to use ___________to find common proteins and amino acids to determine how closely related species are.

• DNA

• Vestigial structures

• Fossils

• Homologous structures

Multiple Choice

By looking at the genes of some animals we can determine which living species are most closely related to each other. This also reveals which species most recently diverged from their common ancestor.

Based on the partial gene segments shown, which pair of animals are genetically most closely related and therefore most recently diverged from their common ancestor?

• Chimpanzee and Mouse

• Rat and Mouse

• Rat and Chimpanzee

Multiple Choice

The picture shows a/an ___________

• homologous structure

• vestigial structure

• analogous structure

Multiple Choice

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor
• Have very similar skeletal structures
• belong to the same species
• must range great distances to eat

Multiple Choice

What is this an example of?

• Homologous structure

• Analogous structure

• Vestigial organs

• Functional adaption

Multiple Choice

Which of the following is an example of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the tailbone of a human

Multiple Choice

Similarities in bone arrangements, like those in the picture, support the hypothesis that...

• these organisms are not well adapted

• these organisms share a common ancestor

• these organisms all share the same DNA sequences

• these organisms are members of the same species

Multiple Choice

According to the images shown, which species are most related?

• calf and rabbit

• fish and human

• pig and tortoise

• salamander and chick

Multiple Choice

The diagram illustrates an embryonic stage of two organisms.

Which of the following can be determined by observing the embryos shown in the diagram

• The organisms share a common ancestry.
• The organisms belong to the same genus.
• The organisms are native to the same geographic areas.
• The organisms will grow into anatomically similar adults.

Multiple Choice

Which is not evidence for evolution?

• many animals have homologous structures due to common ancestry
• Many animals have vestigial structures from an ancestor
• We can observe changes in life forms by observing the fossil record
• All of these are evidence for evolution
