Art [367]

Evolutionary game theory is a mathematical modeling approach to predicting the outcome of natural selection on behaviours when multiple organisms are interacting.

<h3>What is natural selection? </h3>

According to modern concept of evolution natural selection is not a bloody battle as was emphasized by Darwin and Wallace.

It is a peaceful process that has little to do with, "struggle for existence" or "elimination of unfit" or "survival of the fittest".

Natural selection really means differential reproduction ( some members of the population produce lage no of offspring, some are few and still others none.

Those that produce large no of offspring contribute greater percentage of genes to the gene pool of the next generation than those that produce fewer offspring.

If differential reproduction continues for many generation ,then genes of the individual which produce more offspring will become predominant in the gene pool of the population.

This leads to change in the gene frequency of the population.

Individual which are best adopted to the environment having greater no of surviving ones.

Survival of the organism to the reproductive age and their selection for mating is the important factors which results in differential reproduction.

There are three types of natural selection stabilizing

selection, directional selection and disruptive selection.

Some Eukaryotic cells have internal structures that are able to use photosynthesis to convert light energy into chemical energy
Sauron [17]

Answer:

The endosymbiotic event that brought chloroplast in eukaryotic cells happened after the lineage delivered.

Explanation:

The endosymbiotic theory says that the ancestral cell gains the ability of photosynthesis when it engulfed a photosynthetic bacteria and this bacteria remained in a symbiotic relationship with the ancestral cell and evolved as chloroplast in plants that can perform photosynthesis.

All the eukaryotes do not have this internal structure like chloroplast because this endosymbiotic event must be happened after the divergence of the lineage into different groups. Therefore plant cells have chloroplast and animals cell do not have.
