In the animal kingdom, wild wolves joined hunter-gatherers in East Asia, where canines were domesticated and bred to have increased docility. Over thousands of years, people bred dogs with different desired personality and physical traits, eventually leading to the wide variety of dogs we see today. Phosphorus is necessary for the growth of healthy plants. Scientists are developing plants that can grow in phosphorus-poor soil. Some of these new varieties, produced in a lab, make extra copies of a protein that helps plants obtain more phosphorus from the soil.

Breeding dogs for certain traits is a way of modifying outcomes but today's advances have enabled us to actually change certain outcomes through technology

The process being used to develop these new varieties is most likely: (SC.912.L.16.10)

A. natural selection

B. Conversely, paper chromatography

C. direct harvesting

D. genetic engineering
