Evidence of Evolution Review

Based off of the information in the table, what trait did these animals' common ancestor have?

• Bony skeleton

• Four limbs

• Hair

• Vertebrae

As these embryos continue to develop, what will most likely happen?

• Develop new organs according to the nutritional requirements of each organism

• Share similar habitats

• Develop the distinctive characteristics of their own species

• Continue to closely resemble each other as adults.

Using this cladogram, which animals do not have jaws?

• Lancelets

• Lancelets and Lampreys

• Lancelet, lampreys, and tuna

• All of the have jaws

What type of evidence for evolution does this represent?

• Embryological development

• Fossil record

• Anatomical structures

• DNA sequencing

This image shows the development of two embryos. Based on these images which statement is true?

• Their brains will function the same way after birth

• Their tails and legs are different in the early stages

• Their eyes and heads are similar as embryos

• Their legs will be the same length at birth

Based off of the bone structure of humans and snakes, which of the following can we conclude?

• Humans are an ancestor of snakes

• One of the ancestors of snakes had legs, which they no longer use

• Humans will eventually become snakes

• Snakes have legs that they still use

Based on these DNA sequences, which animal is most closely related to humans?

• Rhesus Monkey

• Mouse

• Dog

Using this fossil record, which statement below is true?

• The T-rex lived before the Devonian fish

• Trilobites lived in multiple time periods

• The mammoth and the T-rex lived close together in time.

• The Devonian fish is the oldest fossil ever found.

What characteristic do all organisms on this cladogram share?

• Loss of opposable thumb on foot

• Four kinds of teeth

• Central eye area

• Downward pointing nose

Why is the fossil record considered the strongest evidence for evolution?

• They provide physical examples of living things changing over time

• Fossils are very easy to find, making this type of evidence very common

• They show organisms developing from early stages of life until they die.
