The cuckoo bird and cowbirds have evolved eggs that closely mimic those of other birds (the hosts). Their young also have characteristics (feather coloration and calls) that mimic the young of those other birds and encourage the host parents to feed them. In response, some hosts have developed the ability to discriminate between their own offspring and eggs, and those of the cuckoos and cowbirds.

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	allopatric speciation
B	adaptive radiation
C	convergent evolution
D	coevolution
E	sympatric speciation

Explanation:

Detailed explanation-1: -Coyotes and wolves occupy different niches, but are also closely related. The entire group of animals known as marsupials (ex.: kangaroos, koalas and platypus) have adapted to having a “pouch” on their bodies, where their young can grow and develop.

Detailed explanation-2: -In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities. VLRs and TCRs/BCRs both serve as antigen receptors, but are evolutionarily unrelated.

Detailed explanation-3: -An organism develops different courtship rituals which do not attract main population this would lead speciation.

Detailed explanation-4: -In allopatric speciation, organisms of an ancestral species evolve into two or more descendant species after a period of physical separation caused by a geographic barrier, such as a mountain range, rockslide, or river. Sometimes barriers, such as a lava flow, split populations by changing the landscape.
