Class 12 - Biology - Evolution Page 142

Answer 1

Hey,

Ur answer is here,

Adaptive radiation means a process that develops new species from a single lineage.

An example :-


Darwin finches, found in Galapagos Island. A large variety of finches is present in Galapagos Island that arose from a single species, which reached this land accidentally. As a result, many new species have evolved, diverged, and adapted to occupy new habitats.
They changed themselves according to their surrounding.

Hope it helps you ☺️

Answer 2

Answer:

• Adaptive radiation is an evolutionary process that produces new species from a single, rapidly diversifying lineage.
• This process occurs due to natural selection.
• An example of adaptive radiation is Darwin finches, found in Galapagos Island.
• A large variety of finches is present in Galapagos Island that arose from a single species, which reached this land accidentally.
• As a result, many new species have evolved, diverged, and adapted to occupy new habitats.
• These finches have developed different eating habits and different types of beaks to suit their feeding habits.
• The insectivorous, blood suc*king, and other species of finches with varied dietary habits have evolved from a single seed eating finch ancestor.
