Students learn how artificial selection can be used to develop new dog breeds with characteristics that make the dogs capable of performing a desirable task.
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- There is a fit between organisms and their environments, though not always a perfect fit.
- An organism’s features reflect its evolutionary history.
- Some traits of organisms are not adaptive.
- There is a fit between the form of a trait and its function, though not always a perfect fit.
- Artificial selection provides a model for natural selection.
- People selectively breed domesticated plants and animals to produce offspring with preferred characteristics.
- Evolution can sometimes be directly observed.
- Inherited characteristics affect the likelihood of an organism’s survival and reproduction.
- Depending on environmental conditions, inherited characteristics may be advantageous, neutral, or detrimental.
- Our understanding of life through time is based upon multiple lines of evidence.
- Scientists use experimental evidence to study evolutionary processes.
- Scientists use artificial selection as a model to learn about natural selection.
