Desert and desert-scrub biomes are characterized by specific types of plant and animal life. Creosote bushes are found throughout areas such as the Mojave Desert. They are used by roadrunners for nesting, and also provide a home for desert tortoises.
The first attempts at domestication of animals and plants apparently were made in the Old World during the Mesolithic Period. Dogs were first domesticated in Central Asia by at least 15,000 years ago by people who engaged in hunting and gathering wild edible plants
