After reading the paragraph below, answer the questions that follow.

The family Felidae (cats) is distributed across Africa, Eurasia, North America, and South America and is hypothesized to have eight major lineages (Panthera, bay cat, caracal, ocelot, lynx, puma, leopard, and domestic cat groups) as shown in this phylogenetic tree, constructed from DNA sequences. Scientists used a molecular clock and fossil evidence to date the divergence of each group. The dates of divergence are provided in the accompanying figure.




The cheetah, which is currently found in Africa, is part of the puma group. Which of the following predictions is most consistent with the evolutionary hypotheses represented in the phylogenetic tree?
◦ The cheetahs evolved from the lynxes between 7 and 9 million years ago while Laurasia was still connected to Gondwana.
◦ All the cats that are currently found in Africa evolved from a common ancestor in Eurasia about 9 million years ago.
◦ A land bridge between North America and Eurasia formed as a result of lowered sea levels between 4 and 7 million years ago.
◦ The common ancestor of all the species in the puma group dispersed from Africa more than 10 million years ago.

Did you know?

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Drying your hands with a paper towel will reduce the bacterial count on your hands by 45–60%.

Did you know?

Intradermal injections are somewhat difficult to correctly administer because the skin layers are so thin that it is easy to accidentally punch through to the deeper subcutaneous layer.

Did you know?

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

Did you know?

Interferon was scarce and expensive until 1980, when the interferon gene was inserted into bacteria using recombinant DNA technology, allowing for mass cultivation and purification from bacterial cultures.
