Examples of this include fishes, seeds, and marine larvae. Relatively little effort or parental care is invested in each individual. In general, this is more typical of r-selected species.

One group, similar to r-selected species, is characterized by smaller sizes, smaller TSA, shorter lifespans, and lower vegetative and reproductive output. These species, such as Z. baoyangense ...

It is one of the processes by which species change from generation to generation, and is a crucial element of the theory of evolution. A classic example of natural selection at work is the origin ...
