The atlantic cod (gadus callarias) is a fish which lays about 5 000 000 eggs in its lifetime. On average, only two of these eggs survive to become adult cod. This promote evolution because the environment selects the most evolved animals to survive that environment.
<h3>What is the evolutionary process?</h3>
Evolutionary processes aim, therefore, to generate greater adaptation of species in an environment. When new species of organisms are formed from gradual changes in preexisting species.
So although there are several eggs initially only those that survived the environment are able and evolved to reproduce, so the evolution of species is carried out.

Answer: Notochord,Nerve cord, pharyngeal gills
Explanation:
1.Presence of notochord that gives them skeletal support this also develops into between Column in vetertebrates.
