Life Science: Genetic Adaptation

The video explains genetic adaptation in animal populations, using the peppered moth in England as an example. Initially, light-colored moths were camouflaged against light tree bark, but industrial pollution darkened the bark, favoring darker moths. As pollution decreased, lighter moths became more common again. The video also discusses human influence on animal traits through selective breeding, using dog breeds as examples. The lesson concludes with a summary and encouragement for a life science test.

What role do genetic traits play in the survival of animal populations?

Discuss the impact of environmental changes on the genetic traits of animals.
