Leeches, ticks, mosquitoes, lampreys, and vampire bats all suck blood. would they form a monophyletic group of close relatives with a recent common ancestor in a phylogenetic tree?

Answer;

No, they would not form a monophyletic group of close relatives with a recent common ancestor.

Explanation;

-This is because their similarities are due to convergent evolution (adaptation to the bloodsucking lifestyle); phylogenetic analysis is based on homologous features, not analogous features.

-Convergent evolution is the process by which unrelated or distantly related organisms evolve similar body forms, coloration, organs, and adaptations. Phylogenetic analysis is based on homologous features, which the above organisms lacks. Homologous traits are those traits that are shared by two or more different species that share a common ancestor.
