Summary Introduction
Introduction: During the nineteenth century, the only method to differentiate among the species is by the comparative morphology. However, nowadays it can be used as a main characteristic of taxonomy. Comparative morphology is the term used to study the anatomical features of an organism including the structure, shape and the various form of an organism. Sometimes the comparative morphology tells about only the anatomical details with no clear functions.

Which situation is most likely an example of convergent evolution? a. Squid and humans have eyes similar in structure. b. Worms and snakes both move without legs. c. Some bats and birds have wings that allow them to fly. d. all of the above
All mammals have tailbones and muscles for moving a tail. Even humans have a reduced tailbone and remnant tail-twitching muscles, though these features have no apparent usefulness. These traits in humans would best be described as (a) convergent structures. (b) fossil evidence. (c) evidence from biogeography. (d) vestigial traits.
