This category is for scientific sites about evolution in biology. Evolution is the process by which living things change over generations. Evolutionary biology is the study of how and why evolution occurs. An organism inherits traits from its parents through the genome. Mutations in these genes and/or the way they are read, or not read, can produce a new trait in the offspring. If a new trait makes these offspring better suited to their environment, they will be more successful at surviving and reproducing. This process is called natural selection, and it causes useful traits to become more common. The theory of evolution by natural selection was first proposed by Charles Darwin in his book “On the Origin of Species”, written in 1859.
