(N/A) $\rightarrow$ Phylogeny refers to the evolutionary history of an organism. It provides insight into the ancestral relationships between different organisms.
$\rightarrow$ While fossil records offer some information,they are often incomplete. Therefore,phylogenetic relationships are determined by integrating data from various fields such as morphology,cytology,genetics,physiology,and biochemistry.
$\rightarrow$ Using these evolutionary relationships as a basis for classification ensures that organisms are grouped according to their natural affinities rather than just superficial similarities,leading to a more accurate and scientific classification system.
