Over a million years ago birds developed as species what does this relate too?

The development of birds over a million years ago relates to the process of evolution, specifically the adaptation and diversification of species from common ancestors. Birds are believed to have evolved from theropod dinosaurs during the Late Jurassic period, showcasing how environmental pressures and natural selection can lead to significant morphological and behavioral changes. This evolution illustrates the broader principles of evolutionary Biology, including speciation and the survival of species through adaptation to their ecosystems.
