It is well known that many species adapt to their environment, but it is usually assumed that only the most highly evolved species alter their environment in ways that aid their own survival. ████████ ████ ██████████████ ██ ████████ █████ ███████ ███████ ███████ ██ █████████ ███ ████████ ████████ █ ███ ████ ██ █████████ ██ ███ ██████████ ████ █████████ ██ ████████ █████ █████████ █████ █████ █████ ██ █████████ ████ ███████ ███████ ███████ ███ █████████ ██ ██████ ████ ███ █████ ███████ ███████ ██ ███ ████████ ██ █████ ██████████ ████ █████ █████ █████ ████ ████████ ██ ██████████ ███ ██ ███ █████ ███████ ████ █████ ████ ████████ █████ ███ ███████ ██ ███ █████ ██ ██ ██████ ███ ████ ████████ ███ █████████
After mentioning the well-known fact that many species adapt to their environment, the author points out a common assumption people make related to this fact: that the only species that modify their own environment to aid their survival are the most highly evolved ones. The author asserts that, contrary to this assumption, this characteristic is actually common. The rest of the stimulus offers a detailed example of certain species of plankton as support for the author's claim.
