Answer:
Option C
Explanation:
Options for the question are
a. It demonstrated that nothing in biology makes sense except in the light of evolution.
b. It demonstrated that species arise from other species.
c. It provided a quantifiable mechanism to explain gradual evolutionary change.
d. It was the first time that change in biological organisms was observed.
e. It was not very important to evolutionary biology.
Solution -
The term modern synthesis by coined by Julian Huxley and the goal of this synthesis was to understand and determine how genetics bring evolutionary changes in a population and with this objective it combined the Darwin’s theory of evolution and Mendel’s work on heredity. Later on scientist Dobzhansky under this synthesis found that genetic mutation causes variation through the process of natural selection and hence lead to evolutionary changes in a population even if they are isolated for a long time.
Hence, option C is correct
So we can easily classify animals and distinguish their relationships
Unlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele’s adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100\%100%100, percent frequency) of a harmful allele in a population.
The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population. These “sampled” populations often do not represent the genetic diversity of the original population, and their small size means they may experience strong drift for generations.
Well what I notice right here. He correct, because if the moon is completely dark that is called a new moon. Its fine really! The moon is away from the sunlight so if its rotating and its not from the sun its just a new moon. And the OTHER side is showing brightness. I hope this helpsss!
