Answer:
According to Darwin's theory of evolution, new species evolved as a result of natural selection.
Explanation:
- Darwin proposed that speciation could readily occur through the prolonged action of Natural selection.
- Natural selection allows the 'survival of the fittest' i.e. a more fit organism will have a better chance of survival than the less fit one.
- The result of Natural selection could be positive,negative or balancing.
- Evolutionary process in which the genetic changes confer a higher fitness to increase frequency of the organism over time in population is called positive selection.
- Evolutionary process in which genetic changes decreases the organism's fitness resulting in its disappearance from the population is called Negative selection.
- It may happen that a mutation benefits hetero-zygotes but not homo-zygotes and alleles maintain a intermediate frequency in population.This evolutionary process is called balancing selection.

Explanation:
I dont think i'm answering your question, but the sun turns into a red giant, and the more it gets bigger it gets, the more closer it is to the planets. Then eats up the the planets later on, and explodes. Dont know if im correct tho sorry
Answer:
a. Determine the allele frequencies of:
f(T) = 0.485 ≅ 0.48
f(t) = 0.515 ≅ 0.52
b. Determine the genotype frequencies of the exposed generation
- F (TT) = 0.21
- F (Tt) = 0.55
- F (tt) = 0.24
the genotype frequencies of the next generation
- F(TT) = 0.23
- F(Tt) = 0.5
- F(tt) = 0.27
