Horses belong to an order of organisms called Perissodactyla, or odd-toed ungulates. The distinguishing characteristics of odd-toed ungulates is that their third, or middle toe, is the largest, while the other four toes are reduced or absent.

Circle the organism below that shares the most recent common ancestor with the modern horse and would also be classified as Perissodactyla.

Which statement best describes the cause of the arrangement of smooth and spikey trilobite fossils observed in the fossil record?

• The smooth trilobites were able to dig deeper into the soil than the spikey trilobites because they did not have protruding spikes that would catch on rocks in the ocean floor.

• Smooth trilobites could no longer blend in with the soil and grew spikes as an adaptation to protect themselves from predators gradually over time.

• The smooth trilobites were not able to compete with the spikey trilobites for food and slowly became extinct as the spikey trilobites became more dominant in the environment.

• A change in the environment caused the smooth trilobites to no longer be well adapted for the conditions. Spikey trilobites were well adapted to the new environment and began to thrive.

Two species of sunflowers grow on either side of a mountain. For a while, the two sunflower populations evolved separately. With the climatic changes, an animal population crosses from one side of the mountain chain to the other, bringing some sunflower pollen with it.

This movement of alleles between the sunflower populations is called ________.

The white tail cattail is a hybrid species of plant that is a result of the cross between the broad-leaved cattail and the narrow-leaved cattail. Over time, the white cattail has established itself in the wetlands of Midwestern states. 

Which of these explains the success of the white cattail? 

• Favorable genes from parental generations provide advantageous characteristics to the hybrid species.

• Inherited traits passed on from parental generations make hybrid species more susceptible to disease. 

• Hybridization produces offspring traits that allow different species to survive in extreme environments.

• Hybrid species display more adaptations due to their reduced genetic diversity.

Students examine images of a certain species of bat commonly found in Texas. Using the bat dichotomous key, they conclude that the bat species is a Mexican free-tailed bat due to its large, round ears.

Based on the dichotomous key, in addition to the shape of the bat's ears, which other set of features should the students look for to confirm the identity of the bat?
