Increasing specialization of structure and function among animals of the same class or order for survival in new and different environments is called "phylogeny".
<u>Option: B</u>
<u>Explanation:</u>
- The analysis of evolution, diversity and the inter-connection among individuals or groups of organisms like species is understood as phylogeny.
- First one to apply the term phylogeny was German Biologist Ernst Heinrich Haeckel.
- With the help of estimation techniques of phylogenetic, such relationships were explored to test identified heritable traits, like DNA sequences or morphology under a framework of evolution of those characteristics.
- The detailing of species, their naming and grouping is understood as taxonomy. It is abundantly guided by phylogenetics, but maintains a field isolation from the scientific and logical.
- Based on the taxonomy school the extent to which taxonomies rely on phylogenies.

Whale shark reproduction can be by laying eggs that is also called oviparity where the female deposits eggs in the algae or rocks. The embryos formed inside the eggs and feed on the yolk. They can also reproduce through viviparity which means by giving birth just like mammals wherein they are born fully formed. This reproduction process is through the placental link to the eggs wherein the yolk sac grows within a placenta that is connected to the wall of the uterus and gives the offspring the nutrients vital for their growth. Another reproduction process is through Ovoviviparity where eggs are formed inside the mother where the eggs hatch within the oviduct of the female and the young feed on the egg yolk of the yolk sac and the fluids that the walls of the oviduct secrete since the mother does not provide any food directly. Once the eggs are ready, eggs hatch inside the mother and it pups keep getting food from their surroundings until they are fully developed. The number of their offspring and the length of the gestation periods varies according to the species. Probably a female of some species may have only two offspring, but some other species may have between forty and eighty. The small sharks have shorter gestation period compared to large species that last from three to four months or up to more than two years. The large ones reproduce every two years, while the little ones have offspring each year. This is why the reproduction process of whale shark is not known in detail.
