Consider the phylogeny below, which traces the history of sexual dimorphism in a hypothetical group of fish, with black lineages being dimorphic (different male and female forms) and white lineages being monomorphic. colored fins have arisen four times in the group, as marked by black bars. what does this pattern suggest about firn coloration and dimorphism? a. colorful fins are just as likely to arise in monomorphic lineages as in dimorphic lineages. b. the evolution of colorful fins is concentrated in dimorphic lineages. c. changes in coloration are randomly distributed across the tree. d. the combination of colorful fins and dimorphism leads to speciation e. colorful fins and sexual dimorphism are probably evolving independently.

Which of the following best describes the purpose of technology?
