Chapter 26, Problem 9TYU
SCIENTIFIC INQUIRY • DRAW IT (a) Draw a phylogenetic tree based on characters 1-5 in the table below. Place hatch marks on the tree to indicate the origin(s) of characters 1-6. (b) Assume that tuna and dolphins are sister species and redraw the phylogenetic tree accordingly. Use hatch marks to indicate the origin(s) of characters 1-6. (c) Determine how many evolutionary changes are required in each tree. Identify the most parsimonious tree.

Concept Check Darwin proposed the theory of natural selection as the mechanism of evolution based on three observations about nature. Which of the following were part of Darwin's observations? a) Populations have the potential to produce more individuals than the environment can support. b) Individuals in some populations have varied characteristics. Variation in individuals appears to be inherited. d) all of the above © 2018 Pearson Education, Inc.arrow_forwardThese (1) are remnants of what was once useful to the ancestors of the species. Furthermore, we can infer from the distribution of related species across the Earth the connections between ancient landmasses.
