In AP Environmental Science, domestication is the process of selectively breeding and managing wild organisms for human benefit, which often reduces their genetic diversity and can negatively affect wild populations of related species.
Domestication is what happens when humans take a wild plant, animal, or insect and breed it over generations to get traits we want, like more meat, sweeter fruit, or honeybees that pollinate our crops. The catch is that to get those specific traits, we narrow the gene pool. Domesticated species end up genetically similar to each other, which makes them less able to handle disease, pests, or sudden environmental change.
In the CED, domestication shows up under 9.10 Human Impacts on Biodiversity as one of the ways human activity chips away at biodiversity. It connects to the bigger HIPPCO framework (EIN-4.C.1), especially over-exploitation and habitat changes tied to agriculture. The key idea is that managing organisms for our economic benefit can backfire on wild populations, for example when domesticated honeybees compete with or spread disease to wild native pollinators.
Domestication lives in Unit 9: Global Change, specifically topic 9.10, and supports learning objective AP Enviro 9.10.A: explain how human activities affect biodiversity and strategies to combat the problem. It's a concrete example of the broader theme that human economic activity has ecological costs. When you reason about why biodiversity is declining, domestication is one of the human-driven causes you can point to, and it ties directly into the HIPPCO factors (EIN-4.C.1) the exam expects you to know.

Over-exploitation (Unit 9)
Domestication and over-exploitation both fall under human pressures on biodiversity, but they pull in opposite directions. Over-exploitation removes too many wild individuals; domestication multiplies a narrow few. Both end with lower genetic diversity in the system.
Habitat destruction (Unit 9)
Domesticating crops and livestock drives the clearing of land for farms and grazing. So domestication is often the reason habitat gets destroyed and fragmented in the first place, linking it to EIN-4.C.2.
Invasive species (Unit 9)
Domesticated species don't always stay put. When managed honeybees or farmed animals escape or out-compete native ones, they act a lot like invasive species, another HIPPCO factor in EIN-4.C.1.
Expect domestication in multiple-choice questions that ask you to identify an example (like selectively breeding crops or managing honeybee colonies) or to explain a consequence. A classic stem asks how honeybee domestication impacts biodiversity, and the answer is that managed bees can compete with and spread disease to wild native pollinators. Another common angle: why do domesticated species have less resilience to environmental change? Because selective breeding narrows their genetic diversity. No released FRQ has used this term verbatim, but it's solid evidence for free-response prompts asking you to explain human impacts on biodiversity under 9.10.A.
Over-exploitation means harvesting wild organisms faster than they can replace themselves, like overfishing. Domestication means breeding and managing organisms under human control. Both reduce biodiversity, but one drains wild stocks while the other concentrates traits in a controlled population.
Domestication is selectively breeding and managing wild organisms for human economic benefit.
Because it narrows the gene pool, domestication lowers genetic diversity and makes species less resilient to disease and environmental change.
Domesticated species like honeybees can harm wild populations by competing with native pollinators or spreading disease.
It fits under topic 9.10 and supports learning objective AP Enviro 9.10.A on human impacts to biodiversity.
Domestication connects to HIPPCO (EIN-4.C.1) and often drives habitat destruction through expanding agriculture.
It's the process of selectively breeding and managing wild organisms for human benefit, such as crops, livestock, or managed honeybees. On the exam it's framed as a human activity that reduces biodiversity, mainly by lowering genetic diversity.
Bad, in the AP context. Even though it benefits humans economically, domestication narrows genetic diversity and can hurt wild populations, like when domesticated honeybees compete with and spread disease to native pollinators.
Because selective breeding concentrates a few desired traits and shrinks the gene pool. Low genetic diversity means fewer individuals can survive new diseases, pests, or climate shifts, so the whole population is more vulnerable.
Over-exploitation is harvesting wild organisms faster than they can recover, like overfishing. Domestication is breeding and managing organisms under human control. Both lower biodiversity, but over-exploitation drains wild populations while domestication concentrates traits in a managed one.
Managed honeybee colonies can out-compete wild native pollinators for resources and spread diseases to them, reducing native pollinator populations. That's why it shows up as an example of a human impact on biodiversity under topic 9.10.
