Question

Anthropogenic actions have caused evolution of species. explain with the help of two examples.

Answer 1

Hint: Actions that are created or initiated by people and usually have harmful effects is called anthropogenic actions. Anthropogenic actions have caused evolution of species in a very short period of time.

Complete answer:
1.Development of antibiotic and drug resistance - we continue to use antibacterial drugs. Over time, some microorganisms develop resistance to these drugs, altering or modifying their structure. Those with resilience were naturally chosen because they survived. Thus, the development of drug resistance in microorganisms is an example of natural selection. , this type of natural selection takes place over a short period of time, that is, months or years, rather than centuries
2.Industrial Melanism- Before industrialization in England, white-winged moths were more common than black-winged moths. However, after industrialization, everything changed. In the post-industrial era, the number of black-winged moths in England increased significantly compared to white-winged moths in the same region.
But after industrialization set in, the pollution increased and the tree trunk became darker in color the reason for the darker color of the trunk was
(a)Smoke and deposition of shoot.
(b)Due to absence of the lichens on the tree trunk because lichens do not grow in polluted areas.
As a result of this white-winged moth not able to camouflage, therefore, were predated by birds , this results in the decrease in the number of white-winged moths.
This suggests that in mixed populations with different strains of moths, better adaptation will survive and produce more offspring. Or you can say that it was chosen by nature.

Note: It is important to remember that in industrial Melanism no variant(type) of moth is completely wiped out.
Development of herbicide resistance in wild varieties is also an example of anthropogenic action that has caused evolution of species.
Evolution is a stochastic process which is based on chances of even in nature and chances of mutation in organisms.
