Explanation:
Answer:
The Scientific Method is a series of steps used by a scientist or just a regular person to help them complete an experiment. It consists of systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses. It could also be used to study and learn new and different things.
A population of birds colonizes an area in which the insects upon which they feed live inside trees. Which of the following events accounts for an observed increase in average beak size in the bird population over time?
a. Decreased fitness of the insects, allowing the birds to catch them more easily
b. Increased fitness of large-beaked birds, leading to natural selection
c. Increased fitness of the large-beaked birds, creating a new species
d. Decreased fitness of small-beaked birds, creating a new species
Increased fitness of large-beaked birds, leading to natural selection. So, the correct option is (B).
What is Natural Selection?Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.
For Darwin, natural selection is a drawn-out, complex process involving many interrelated causes where it requires variation in populations of organisms. For the process to work, at least some of that variation must be heritable and passed on to the organism's descendants in some way.
Example of Natural selection is birds with larger beaks are better able to survive in the new environment.
Thus, increased fitness of large-beaked birds, leading to natural selection. So, the correct option is (B).
