The diagram below shows finches found on the Galapagos Islands. The beaks of the finches show how they are adapted to eating various types of food. The common ancestor of all these birds was found on the mainland of South America. FinchesThis process of the formation of new forms from an ancestral species in response to differing habitats is called:

a symbiotic relationship with the mitochondria

cells spend most of their time in interphase

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
