Answer:
The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
Explanation:
Answer:
Evolution.
Explanation:
It might have acquired the ability to cause disease due to evolution. Due to evolution, the harmless bacteria can turn into infectious pathogens that cause diseases. Evolution is the change in the characteristics of a species over several generations due to the process of natural selection. This evolution in the bacteria occurs due to changing of environmental conditions which changes the genetic makeup of that harmless bacteria and turn into infectious pathogen.
