In artificial selection ‘Selective Breeding’ is a necessary process due to earth’s population. Why is artificial selection important for humanity? Artificial selection has been a key factor in the evolution of:
- Photosynthesis
- For nature
- To produce bigger and better food to feed all humans.
- Nature can create better organisms
Hint:
Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
The correct answer is: To produce bigger and better food to feed all humans.
To produce bigger and better food to feed all humans artificial selection is important
Artificial selection has long been used in agriculture to produce animals and crops with desirable traits. The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection.
