Answer: 2. The plants and animals diffused to a region with climate and geography similar to that of their point of domestication.
Explanation:
Knowledge of the centres of origin of plants and animals has increasingly improved. it is much harder to identify the way through which plants and animals were distributed, by what roads and what means they arrived at one place or another, who brought them and who diffused them.
One very important note is that plants and animals diffused to a region with climate and geography similar to that of their point of domestication which makes them survive and develop to the stage of harvest.
Much of Earth's water is thought to have come from asteroids impacting the planet early in its history. Image via NASA/Don Davis. The surface of the very young Earth was initially an ocean of magma. Hydrogen and noble gases from the solar nebula were drawn to the planetary embryo, forming the first atmosphere.
This is the picture of Pangea!
