Adaptive radiation is the phenomenon by which an ancestral group of organisms diversifies into various related forms, adapting to different environments.

Q. Development of different functional structures from a common ancestral form is called adaptive radiation.

Q. Adaptive radiation means evolution from ancestral type to

Q. Assertion :Darwin's finches of Galapagos islands have different types of modified beaks according to their food habits. Reason: Adaptive radiation, leads to development of different functional structure from a common ancestral form.

Q. Arrange the different parts in the correct sequence to form a meaningful sentence/paragraph.
P : Fossil evidence suggests that the mammals
underwent adaptive radiation to produce the
range of mammal types extant today.
Q : Adaptive radiation, in the life sciences, refers
to the differentiation (or savageness) of one
or a few species into many to till a large number
of related ecological niches by adaptation
R : Thus the first bird species may have given rise
to many more bird species by adaptive radiation
S : Typically, a species adapts to colonize a new
habitat and, this adaptation opening up a new
range of niches, adapts again to fill the new
niches which are presented.
