When the starfish were removed from the area as part of an experiment, the mussel population swelled and crowded out other species. The biodiversity of the ecosystem was drastically reduced. Payne's study showed that identifying and protecting keystone species can help preserve the population of many other species.

i would like that for me lol
Explanation:
Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement.
A skin cell should proliferate very well and at the same time be protected against UV radiation, it would be important to have a function in which is cell is flexible, but also comparably hard.
A muscle cell needs a huge metabolism, a certain way to function, UV protection on the other side is really not its business.
In biology, evolution is the change in the inherited traits of a population from generation to generation.
Common traits that have evolved in creatures are multicellular, heterotrophic, obtaining their energy by consuming energy-releasing food substances, reproduction and changes in cell structures.
