Q. Evolutionary history of an organism is known as

AFMCAFMC 2008Evolution

Solution:

Phylogeny (Gr. phylon=tribe or race; geneia $=$ origin) is the origin and diversification of any taxon or the evolutionary history of its origin and diversification. It is usually represented as a diagrammatic phylogenetic tree (that traces putative evolutionary relationships) ie, dendrogram.
Palaeontology is the study of fossils. Ontogeny is the whole course of an individual's development and life history.
