Which organism below is a member of the phylum chordata?

Using Table 4, Which two organisms are the most closely related and why?

It was only recently discovered that giant pandas are much more closely related to bears, than to racoons. Before this, many scientists believed that they were large members of the racoon family. What is the best piece of evidence, that was probably used to re-classify giant pandas with bears?

Which is an accurate statement of the differences between spontaneous generation and biogenesis?

Fish obtail oxygen through what structure

Which of these is most correct, with regard to the way that giraffes came to have long necks?

The theory of evolution by natural selection was developed independently by:

While looking for fossils on an eroded hillside, you discover fossil coral and fish in one layer. In a layer just above, you find the fossil imprint of a fern frond and some fossil moss. Assuming the rock has not been disturbed, which of the following is the most probable conclusion?

Using the scenario below, determine the independent variable.

Peter Grant, the department chairman of evolutionary biology at Princeton University, and his wife have been doing research on Daphne Major, one of the islands in the Galapagos. They have been studying the effect of drought on the beak depth in the finch population on Daphne Major.

In 1977 and 1982, Daphne Major suffered from serious droughts. During these times Grant recorded that beak depth increased. In other years, there was plentiful rainfall. During these years, Grant recorded that beak depth deceased. In the years when the rainfall was plentiful, many grasses and herbs produced an abundant supply of small seeds. Some other plant species produce a few number of large seeds.

According to Diagram 3, what is the closest relative of humans?

The similarity of structures labeled in A in Diagram 2 suggests that organisms

During the fall reproductive season, the belly of a male brook trout becomes bright orange. The orange belly provides some camouflage and helps attract females.

This trait evolved in brook trout because, compared to males with pale bellies, males with bright orange bellies are more likely to

A biologist analyzes the DNA sequences in three different organisms. The biologist finds that organisms A and B have almost the exactly same DNA sequences. The DNA sequences in organism C are very different. All three organisms are primates. This information allows the biologist to infer that

Which of the four types of land plants do NOT have vascular tissue

Accoridng to the information in Table 1, which individual is best adapted to their envirnment?

Which statement is insufficiently supported by Darwin's theory of natural selection?

Which characteristc distinguishes Fungi from Plantae?

Which group of organisms is believed to have been the earliest to evolve?

Which characteristic listed below is unique to mammals

The thylacine is an extinct marsupial. Despite having a pouch like kangaroos, the thylacine developed large canine teeth and a dog-like body, and used to be a major predator in Australia before becoming extinct.

The golgen jackal, a predatory wild dog native to a similar environment in Africa. Even though jackals are placental, and have babies the way humans do, they still look very similar to the thylacine.

What type of evolution do the thylacine and jackal have in common?
