Transposable elements are significant features in the genomes of almost all eukaryotic organisms. The accumulation of these elements in various species can help determine their relatedness. Table 1 indicates the presence (+) or absence (−) of 5 segments of DNA that have been moved by transposition (transposons) in 6 primate species. Table 1. Presence of absence of 5 transposons in primate species Species 1 2 3 4 5 Human - + + + + Bonobo + + + + + Chimpanzee + + + + + Gorilla - - + + + Orangutan - - - + + Gibbon - - - - - Which of the following best predicts how phylogenetic relationships might be revised if transposon 1 was not found in chimpanzees?

A number of different phylogenies (evolutionary trees) have been proposed by scientists. These phylogenies are useful because they can be used to

The tree starts with a branch, from the bottom left to the top right of the tree. Halfway up the branch, it splits into two medium branches. The left medium branch splits to form two smaller branches labeled, from left to right, One and Two. The right medium branch splits to form two smaller branches labeled, from left to right, Three and Four. Based on morphological characteristics, the phylogenetic tree above has been developed for species I, II, III, and IV. DNA sequencing has recently been completed for a particular gene found in all four species. The sequencing will provide additional information for answering which of the following questions?

According to the data presented on this phylogenetic tree, is the sun bear more closely related to the polar bear or to the sloth bear?
