beginnings of biology (scientific method, natural selection, patterns, evolution)
natural selection
Natural selection is the process by which organisms with adaptive properties that are well-suited to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations. It is a key mechanism of evolution.
evolution
Process by which species change over time through genetic variation and natural selection. It leads to the development of new species and the extinction of others.
