Which of the following best explains the diffusion of plants and animals from their hearths of domestication? A. Animals were domesticated before plants and diffused rapidly from their hearth of domestication through contagious diffusion because they were mobile and moved easily from place to place.

B. Domesticated plants spread through wind-borne dispersal of seeds from their original hearth, expanding slowly until a vast region was covered with new plants.

C. Both domesticated plants and animals spread across the globe through contagious diffusion in early years by farmers and traders, and later by relocation diffusion through European exploration and colonialism.

D. The diffusion of plants and animals was limited to areas close to each hearth of domestication because the newly developed plants and animals could not readily adapt to different soil types.

E. The diffusion of plants and animals was dependent on nomadic traders who traveled between agricultural villages because early farmers were sedentary and did not travel to other areas.

The best explanation for the diffusion of plants and animals from their hearths of domestication is option C.

Contagious diffusion in the early years was a way of spreading from one person to the other. These farmers and traders exchanged the domesticated plants between themselves.

The relocation diffusion happened as the European explorers moved from their original continents to other continents. They got to these new areas and they got hold of the new plants and the animals that existed in these areas.

They also traveled with theirs too.

C. Both domesticated plants and animals spread across the globe through contagious diffusion in early years by farmers and traders, and later by relocation diffusion through European exploration and colonialism.

Explanation:

At first, domesticated plants and animals were spread via contagious diffusion which is what happens when people in a certain area or locale come into contact with another.

When the Europeans began to explore and colonise the rest of the world, they engaged in relocation diffusion by taking the plants and animals they knew to the new areas and then taking the plants and animals from the new areas back to Europe. This was how domesticated plants and animals spread across the world.
