"Evolution experiments" refers to scientific studies in which researchers observe and analyze how living organisms change and adapt over time. Full definition
In their laboratory evolution experiment, the scientists have shown for the first time that evolutionary adaptations to multiple stress factors do not necessarily interfere with each other. (sciencedaily.com)
After one year, growth rates relative to the control cultures had increased slightly, but later hardly any increase could be detected — which is a contrast to many other evolution experiments. (sciencedaily.com)
However, the longest evolution experiment that has been conducted with this organism so far shows, that the potential for adaptation is not as large as initially expected. (oceanacidification.de)
