A student has written a paper about a deer population that was separated when a canyon developed between members of the group. In her paper, she showed that the two groups adapted differently and can no longer interbreed. What would be the best title for her paper?
Jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. Which of these would make the best project?
A male cardinal’s red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
Why do species evolve during adaptive radiation?
Charles Darwin hypothesized that some individuals would be better equipped for survival than others, and that those that were less equipped would not survive. Darwin formulated this hypothesis based on the work of which scholar?
Which best illustrates a result of natural selection?
Horses and zebras can be bred to produce a zorse, which is infertile. Which is most likely the reason zebras and horses are considered separate species?
Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation allow for the change of gene pools over time?
A biology teacher asks students to give examples of genetic variations that support the idea that changes in a population’s environment affect genetic variation. Which is the least supportive example?
In 2002, the fossil of a four-winged dinosaur was discovered in China and named a microraptor. What was the significance of the discovery?
Which best defines a gene pool?
Which type of selection leads to increased phenotypic and genetic variation?
Which of these is an example of reproductive isolation?
A scientist is studying the population decline of cheetahs in Africa and the Middle East over the past several decades. Which best describes this situation?
Henry was studying two populations of the same species of lizards. One population lived on an island and the other lived on the mainland. Both populations were affected by a hurricane that hit the island and the mainland with equal force. A year later, Henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. Which best describes a conclusion he might have reached?
Which best describes biogeographic isolation?
Which best describes horse breeding?
Archaeopteryx fossils show that the animal had feathers like a bird. It also had a bony tail, teeth, and claws on its wings like a reptile. Scientists claim this is evidence of a common ancestor. What makes this a sound claim?
Which of Charles Darwin’s main points is depicted in the image?
Which statement best explains the relationship between HbS allele frequency and malaria endemicity in Africa?
