use available evidence to describe the changes in a species of grain or animal as a result of domestication and agricultural processes
Background
During domestication, livestock decreased in size from the wild varieties to make them less likely to do harm. Plants generally were bred to be bigger and easier to eat. Grain became less likely to be spread by the wind and more likely to stick closely in the heads of the plants so they could be harvested. Wild grain matures at different times but domesticated grain is bred to mature at the same time to make harvesting easier.
- Obtain evidence from your teacher or use the links below and the background information above.
- Use available evidence to formulate cause and effect. Look at the effects of human and natural activities such as natural hybridisation and human intervention in the production of domesticated species.
Here are some starting points.

- After you have done some research decide whether you want to describe a grain or an animal and which species of the grain or animal to study.
- One way to present the information is as an oral presentation designed to inform other members of your class.
