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.
According to the phylogenetic tree, what is the best explanation for why members of the Felidae are found on nearly all the major continents?
◦ Species selection for fast predators was common on most continents.
◦ The Felidae diversified in the Mesozoic, when the Earth's continents were still close together.
◦ Divergence and migration occurred multiple times, in multiple locations.
◦ The common ancestor of the Felidae evolved on Pangaea.
