- Describe limitations of the biological species concept.arrow_forwardWhat problems does horizontal gene transfer cause for evolutionary biologists? a. It can make the reconstruction of phylogenetic trees difficult because it can obscure phylogenetic relationships. b. It can cause physiological problems in some organisms, making it hard to study them. c. It can make breeding between different individuals of the same species difficult. d. Because it is the transfer of genes between the same species, it can make individuals look more similar than they actually are. e. All of the above.arrow_forwardThe biological species concept is based on the assumption that species are reproductively isolated and do not share genes. And yet a number of organisms that are considered different species hybridize (mate and exchange genes). Hybridization between different species is more common in plants than in animals.
