In Australia, marsupials and placental mammals have evolved to share many similar characteristics. This type of evolution may be referred to as
2013 NEET 1 question
-
The process by which organisms with different evolutionary history evolve similar phenotypic adaptation in response to a common environmental challenge, is called:When unrelated organisms develop similar adaptations in response to the same environmental challenge, it is called convergent evolution.
2007 AIPMT-PRE 1 question
-
What is common to whale, seal and shark?Whale and seal are mammals, while the shark is a cartilaginous fish; they are not closely related.
All three live in the sea and have developed similar adaptations for swimming, such as a streamlined body and limbs modified into flippers or fins.
Unrelated organisms acquiring similar features because of a similar habitat is called convergent evolution, and the similar structures are analogous organs.
So convergent evolution is common to the whale, the seal and the shark.
Homoiothermy is found in the whale and the seal (mammals) but not in the shark, which is cold-blooded.
Thick subcutaneous fat (blubber) is a feature of the marine mammals and not of the shark.
So the answer is convergent evolution.

-
Similarities in organisms with different genotype indicate : -When unrelated organisms (with different genetic make-up) live in similar environments, they may evolve similar features to meet similar needs.
This is convergent evolution, which produces analogous structures, e.g. wings of birds and insects, flippers of whales and fins of fish.
Divergent evolution is the opposite: related organisms become different (homologous organs).
So similarities in organisms with different genotypes indicate convergent evolution.
