Question

Increasing specialization of structure and

Answer 1

Increasing specialization of structure and  function among animals of the same class or  order for survival in new and different  environments is called "phylogeny".

Option: B

Explanation:

• 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.
