Both tuna (fish) and dolphins (mammals) have a streamlined body shape and large tail
fins that they use to move through the water. Many other anatomical and DNA
sequence data indicate, however, that tuna and dolphins are not closely related from an
evolutionary perspective. The latter data suggest that _____.
a. Anatomical data is useless for classifying evolutionary relationships.
b. Organisms that live in the same environment (for example, water) will always look the
same.
c. Tuna and dolphins faced similar selective pressures on body shape and tail fins for
reproductive success. d. These organisms are, actually, closely related evolutionarily -
Correct Answers -c. Tuna and dolphins faced similar selective pressures on body shape
and tail fins for reproductive success.
Some organisms, such as a chimpanzee and a human, have many similarities. Others,
such as a chicken and an oak tree, have fewer similarities. What is TRUE about the
ancestors of these organisms?
a. Chimpanzees and humans share a common ancestor with each other, but chickens
and oak trees do not share a common ancestor with each other.
b. Chimpanzees and humans share a common ancestor with each other, and chickens
and oak trees share a common ancestor with each other, but chimpanzees and humans
do not share a common ancestor with chickens and oak trees.
c. Because chimpanzees, humans, chickens, and oak trees are separate species, none
of them shares a common ancestor with any other.
d. Chimpanzees, humans, chickens, and oak trees all share an ancient common
ancestor. - Correct Answers -d. Chimpanzees, humans, chickens, and oak trees all
share an ancient common ancestor.
