What is convergent evolution and how is it different from horizontal gene transfer?
What will be an ideal response?
Answer: Convergent evolution is the evolution of the same or similar function that occurred independently more than once. Organisms that have evolved the same function through convergent evolution utilize different enzymes or structures to perform the same function. Horizontal gene transfer is the transfer of particular genes or set of genes that confer the same function on another group of microorganisms. Both processes result in divergent species (species lacking a recent common ancestor) performing the same function.
