Verified step by step guidance1
Examine the phylogenetic tree provided in the problem. A phylogenetic tree is a diagram that represents evolutionary relationships among species based on shared common ancestors.
Identify the position of *Bos taurus* on the tree. Look for the branch or node where *Bos taurus* is located.
Determine which species shares the most recent common ancestor with *Bos taurus*. The species that is connected to *Bos taurus* by the shortest branch or node is the most closely related.
Compare the positions of *Sus scrofa*, *Bos indicus*, *Capra hircus*, and *Ovis aries* relative to *Bos taurus*. Focus on the branching points to see which species diverged most recently from *Bos taurus*.
Conclude that the species sharing the most recent common ancestor with *Bos taurus* is the one most closely related. This conclusion is based on the principle that closer nodes indicate more recent evolutionary divergence.
