Process by which several new species evolved from a common ancestor is called
A
convergent evolution
B
divergent evolution
C
cladogram
D
phylogeny
Explanation: 

Detailed explanation-1: -Divergent evolution represents the evolutionary pattern in which species sharing a common ancestry become more distinct due to differential selection pressure which gradually leads to speciation over an evolutionary time period.

Detailed explanation-2: -In evolutionary biology, divergence pertains to an evolutionary process wherein a population of an inbreeding species diverges into two or more descendant species that have become more and more dissimilar in terms of forms and structures. This divergence results from their adaptation to their environment.

Detailed explanation-3: -Divergent evolution occurs when two separate species evolve differently from a common ancestor. Speciation is a result of divergent evolution and occurs when one species diverges into multiple descendant species.
