Tree 1 Tree 2 Tree 3 outgroup A В C outgroup В C A outgroup A We have gathered some morphological data on three species of mythical mammals and the outgroup; these data are presented in the table below. Species Number of toes Eye color Tail Number of molars Outgroup 4 Brown Present 12 A 5 Blue Absent 10 4 Blue Present 12 Blue Absent 10 Now our task is to discover which of the three trees above is the most parsimonious, representing the most likely pathway of evolution. We determine the best tree by fitting the data in the table to each tree and calculating the number of evolutionary changes that are required. To facilitate our calculations, we will use the table below. The numbers in the table indicate the number of evolutionary changes that are required for each character in each tree.

Primate evolution

Primates are a relatively new species and first appeared in the fossil record nearly 55 million years ago. They may have originated as far back as the cretaceous period. Their fossils were observed in North America, Asia, and Europe. Long before the first monkeys and their prosimian relatives developed, most animal species thrived and died. The first primates did not exist until about 50-55 million years ago, even though the planet is 4.54 billion years old and the first life goes back at least 3.5 billion years. Dinosaurs had been extinct for 10 to 15 million years when this happened.
