Grasshoppers and honeybees both have antennae. They are used for different purposes but are arranged similarly in structure. What type of structure is this?

• Homologous structure

• Analogous structure

• Vestigial structure

• None of these

Answer explanation

Homologous structures are arranged in similar ways. This suggests that the organisms share a common ancestor.

In the past, giraffes had to continually stretch their necks to reach the plants on tall trees. Which scientist would believe that because they stretched so much, they would be able to have offspring with long necks?

• Darwin

• Lamarck

• Wallace

• Einstein

Answer explanation

Lamarck believed acquired traits could be passed on to offspring -- but he was WRONG

Green and brown beetles live on trees. The green beetles are more easily seen by birds and eaten. Brown beetles are more likely to survive longer, reproduce, and pass on their traits. What is this process called?

• Natural Selection

• Variation

• Inheritance of Acquired Traits

• Overproduction

Answer explanation

This is the theory that Darwin (and Wallace) believed to be true!

An elephant's trunk is long and able to move in such a way that the elephant can pick things up (like food and water!). This is an example of _______

• Adaptation

• Variation

• Acquired Trait

• Cladistics

Answer explanation

A variation that makes an organism more fit for their environment is called an adaptation

Studying the earliest stages of life (like in this picture) is called ______

• Anatomy

• Biogeography

• Embryology

• Phylogeny

Answer explanation

Biogeography is the study of where organisms live now compared to where their ancestors used to live

• Lion & house cat

• Brown bear & platypus

• Brown bear, lion & house cat

• All of them

Answer explanation

Cladograms can also be called phylogenetic trees

Compare the shark, penguin, and dolphin limbs. What type of structures are these?

• Homologous structures

• Analogous structures

• Vestigial structures

• None of these

Answer explanation

The function of all three is to assist in swimming, but the structures are arranged differently. That makes them analogous structures.

Compare the human, horse, dolphin, and bat limbs. What type of structures are these?

• Homologous structures

• Analogous structures

• Vestigial structures

• None of these

Answer explanation

The arrangement of the bones is the same. That makes them homologous structures. Some of their functions are similar, but they don't need to be in order to be classified as homologous.
