Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, a
sattari [20]

Answer: natural selection

Explanation:Natural selection, gene flow, gene drift and mutation are the mechanisms for EVOLUTION.

The dominant purple allele must have been acquired from previous parent gene, by natural selection

Definitely the available   alleles from previous flower population were white and purple flowers. But, because the parents of purple flowers exhibit VARIATION, in their gene pool,  they showed dominance over  the recessive white colour flowers in the same population.  

◼ from Darwin’s observation and deduction, Organisms who acquired certain characteristics from variation  tend to survive than others, and therefore pass these inheritable characteristics to their offspring.

◼Thus the purple flowers dominated the population for the available resources, among the other flowers colours, (competitions) therefore it leads to a stable population in size after a period of time., while the white colour flowers are recessive

◼Darwin concluded that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).

Based on this, natural selection takes place, and the purple flowers with best variation will have selective advantage (dominance)above white colour flowers(recessive).

Consequently, they have higher survival rates compare to white flowers in the population this is   survival of the fittest by natural selection of purple flowers

The frequency of the white colour flower will reduced because of less manifestation of traits from generation to generation from reduced gene pool due to recessive trait, however the frequency of Purple flower will increase because the number of copies of allele of purple flowers is greater than the total number of all the flowers population( white flowers+purple)

D. “The scientific name Asteroidea was given to starfish by the French zoologist de Blainville in 1830. It is derived from the Greek aster, ἀστήρ (a star) and the Greek eidos, εἶδος (form, likeness, appearance). The class Asteroidea belongs to the phylum Echinodermata.”

E. “First, primates have larger eyes than many other mammals of comparable body size (Ross & Kirk, 2007). Having large eyes ensures that a large image is formed on the retina (Walls, 1942; Land & Nilsson, 2002). This large retinal image may then be sampled by many photoreceptors, improving visual resolution. Primates have flexible shoulder joints and and strong clavicles or collar bones that help them use their arms more effectively than other species of animals. Most primate can hold their bodies erect and some species, including humans, can walk on two legs instead of four.”
