The best equipped organism survive which is known as the survival of the fittest.
Over the time due to challenges in the environment the beneficial variation takes place in the organisms and it spreads through the generations and then it gradually changes the whole population.

The organism of the same species have some variation and because of this variation they compete and win against the other member of the same species.
Answer:

Explanation:
Organism in which the embryonic blastopore becomes its anus Deuterostome
<u>Explanation:</u>
The term Deuterostome refers to second mouth. The first opening which is called blastpore becomes its anus in deuterostomes. In protostomes, this first opening will be the mouth. The other name given to these Deuterostomes enterocoelomates. It is the enterocoely from which the coelom of Deuterostom starts emerging and growing.
Chordata, Echinodermata, Hemichordata are the classes of deuterostomes:. The zygote is the one that gets developed first in protostomes and deuterostomes.Radial cleavage occurs in deuterostom in which the division of cells lies either in parallel direction or in perpendicular direction with respect to the polar axis.
