Evolutionary history of an organism is known as -Phylogeny is the evolutionary history of an organism or a group of organisms, showing its origin and its relationships with other groups.
It is usually represented as a branching diagram called a phylogenetic tree.
Ontogeny is the developmental history (life history) of an individual, from the zygote to the adult.
Haeckel's biogenetic law relates the two: ontogeny recapitulates phylogeny.
Palaeontology is the study of fossils.
Ancestry is only the line of descent of an individual.
So the evolutionary history of an organism is known as phylogeny.
