Ecology and Evolution Concepts

This video introduces biology, the study of life and its processes, from cells to ecosystems. It covers the cell as the basic unit of life, major branches like genetics and ecology, and key concepts such as evolution and natural selection. The video also explores genetics, focusing on DNA and inheritance, and ecology, examining organism interactions and environmental challenges. The scientific method and evidence supporting evolution are discussed, emphasizing biology's role in understanding the natural world.
