Divergent evolution leads to homologous structures/organs. Improvement of various practical structures from a typical familial shape because of their movement to various natural surroundings and adaption to new prerequisites is called disparate or versatile radiation. For instance - Darwin's finches of the Galapagos Islands had regular precursors however now have distinctive kinds of adjusted bills as per their nourishment propensity.

Industrial melanism is a supportive mechanism as it provides
1 Defensive adaptation of skin against ultraviolet radiations
2 Drug resistance
3 Darkening of skin due to smoke from industries
4 Protective resemblance with the surroundings
Explanation:
The peppered moth (Biston betularia) occurs in two forms-pale colour moth and black colour moth. Before the industrial revolution occurs that is when pollution is less, the pale colour moth were common as they were not easily identified among the light coloured lichens growing on the trees. But after industries were set-up, which killed off the lichens and blackened the trees with soot. On this dark background, the pale moths were no longer well-camouflaged and were easily caught by birds so black colour moth survives and becomes common. This is an example of natural selection. As the environment selects the black colour moth so their number.

The similar habitat that has resulted in selection of similar adaptive features in different groups of organisms but towards the same function. It explains
1 Divergent evolution
2 Convergent evolution
3 Adaptive evolution
4 Chemical evolution
Explanation:
One can say that it is the similar habitat that has resulted in selection of similar adaptive features in different groups of organisms but towards the same function. An example of convergent evolution is the similar nature of the flight/ wings of insects, birds, pteridosaurs, and bats.

Embryological support for evolution given by Ernst Haeckel includes the
1 Presence of gill slits all over the body in adult human
2 Absence of vestigial gill slits in invertebrates's embryo
3 Absence of vestigial gill slits in human's embryo
4 Presence of row of vestigial slits in embryo of all vertebrates behind the head
Explanation:
Recapitulation theory says that embryological development repeats path of evolution. Gill slits are present in the fishes and the aquatic amphibians and from them gradually the reptiles and mammals have evolved.

Divergent evolution gives rise to
1 Homologous organs
2 Analogous organs
