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.
Answer: C
Explanation:
Use DNA from hair follicles of supposed zoo parents and of the supposed offspring to compare sequences amplified with primers for a highly polymorphic region.
DNA sequencing and comparison is a way for checking if two individuals are closely related. Comparison of the sequence of the parents to the supposed offspring will indicate if indeed there was a relationship or if it was imported.
