LIFE SCIENCE

Detailed explanation-1: -Answer and Explanation: There are new species of plants and animals that have gradually evolved. Therefore, there is a need to reclassify organisms based on their newly found traits. The new species have new traits that never existed before; thus, scientists have come up with new ways of classification.

Detailed explanation-2: -Why are evolutionary relationships important? Evolutionary relationships help scientists determine how a species developed its characteristics and came into its present form. They also help researchers theorize why certain species descended from certain ancestors instead of others.

Detailed explanation-3: -DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.

Detailed explanation-4: -Evolutionary taxonomy, evolutionary systematics or Darwinian classification is a branch of biological classification that seeks to classify organisms using a combination of phylogenetic relationship (shared descent), progenitor-descendant relationship (serial descent), and degree of evolutionary change.
