About thirteen different species of finches inhabit the Galápagos Islands today, all descendants of a common ancestor from the S
outh American mainland that arrived a few million years ago. Genetically, there are four distinct lineages, but the thirteen species are currently classified among three genera. The first lineage to diverge from the ancestral lineage was the warbler finch (genus Certhidea). Next to diverge was the vegetarian finch (genus Camarhynchus), followed by five tree finch species (also in genus Camarhynchus) and six ground finch species (genus Geospiza). If the six ground finch species have evolved most recently, then which of these is the most logical prediction? O O O O A. They should be limited to the six islands that most recently emerged from the sea. B. The chances of hybridization between two ground finch species should be less than the chances of hybridization between two tree finch species. C. They should share fewer anatomical homologies with each other than they share with the tree finches. D. Their genomes should be more similar to each other than are the genomes of the five tree finch species
Species can, given enough time, get affected for various reasons and end up as resulting in two or more different species that have descended from the same point. And the more time goes by, the more difference there will be among their genotypes and therefore fenotypes.
The example given in the question depicts a situation where a single species branched into thirteen different ones and the most logical prediction given the information in the question is that their genomes should be similar to each other than the genomes of the other five species because their evolution into different species is the most recent one therefore more similarities should be present.
The deep sea vent organisms or benthic organisms normally live in dark conditions because of no penetration of sunlight. These organisms in order to colonize ocean surface must develop photo sensory receptors and should adapt to the light conditions along with variation in temperatures and pressure in ocean currents.
The reproductive system is different from other body systems in that the reproductive system functions in the survival of a species while all other body systems function to ensure the survival of the individual.
