Name three human activities that are changing the natural world. Why do these activities make it important to understand evolution? Explain Lamarck's ideas about how organisms changed over time.

Habitat degradation and fragmentation, introduction of exotic species and over harvesting.

These activities disrupt the natural function of a variety of species.

Humans must understand evolution to assess the effect these activities can have on various species and the environment

Overharvesting, this can bring the species to extinction. Destruction of habitat is self explanatory, it can also lead to a lot of inbreeding which comes with mutations and not so good things. Pollution also fits in the same category of destruction of habitat also affecting the oxygen living things breathe.

Its correct on edge

1. Deforestation. Cutting of trees results to the endangered habitats of animals and the soil compaction is becoming less and less.

2. Hunting. Killing animals mercilessly and selling them off reduces their numbers and increase the fear of humans

3. Genetic engineering. Modifying the cell structure of a plant or animal increases possible risk of cancer, toxicity in the soil and others.
