Darwin made adaptation to the environment the key property of evolved living creatures. That's all natural selection can do.

A new study has shown that modern birds are essentially living dinosaurs with skulls that are remarkably similar to those of their juvenile ancestors.

Understanding the genetic diversity within and between populations has important implications for studies of human disease and evolution.

Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution.

Geneticists have made a startling breakthrough while sequencing the genome of a South American butterfly, according to a study published in the May 16 edition of Nature.
