The diagram given below shows four varieties of beaks of finches that Darwin found in galapagos Island. Which statement best explains the variation in the beak of these four species ?
In Australia, marsupials and placental mammals have evolved to share many similar characteristics. This type of evolution may be referred to as:
Name the organism represented by A to F in the illustration.
What is adaptive radiation? Explain with example.
What is adaptive radiation? Distinguish between convergence and divergence development.
Most primitive living mammals which provide an evidence of organic evolution from geographical distribution are found in
Select the option which is an example of adaptive radiation:
Assertion (A): 'Adaptation' for coping with environmental extremes is defined as any attribute of the organism (morphological, physiological, behavioural) that enables it to survive and reproduce in its habitat.
Reason (R): Plant adaptations have evolved over a short evolutionary time and are due to changes that occur in genetic material during acclimatisation.
The correct answer is
When adaptive convergence is found in closely related species. It is called as:
Darwin finches differ with each other on the basis of :-
Flying squirrel and flying phalanger represent the phenomenon of
Evolution of different species in given area starting from a point and spreading to other geographical area is known as :
