Humans have had major impacts, both intentional and unintentional, on populations and ecosystems. Human actions have driven change in ways that provide evidence for evolution. Darwin used examples of human impacts on organisms to support the concept of natural selection.
A
DNA sequencing.
B
Domestication of plants and animals.
C
Overhunting.
D
Use of microscopes.
Explanation: 

Detailed explanation-1: -Numerous examples of this human-induced contemporary evolution have been reported in a number of ‘contexts’, including hunting, harvesting, fishing, agriculture, medicine, climate change, pollution, eutrophication, urbanization, habitat fragmentation, biological invasions and emerging/disappearing diseases.

Detailed explanation-2: -Which of the following human activities, according to Darwin, demonstrates that selection can cause significant changes to species? DNA sequencing.

Detailed explanation-3: -Much of our impact on evolutionary processes is due to activities that cause declines in species populations, including: Anthropogenic climate change, including global warming. Habitat loss, often from agricultural activities, deforestation, and/or urbanization. Hunting and fishing for food or sport.
