Under the Môller house in the 1930 experiments (Plates 3, 4 and 5) the glass roof would prevent radia- tional cooling of the plants outside the water-filter. To this extent the experiments in 1930 provided controls lacking in the 1931-1934 experiments.

Web6 de mar. de 2024 · The long-term evolution experiment is one of the most exciting studies on the feasibility of evolution to produce complicated metabolic systems and new systems of information within cells. Evolution holds that mutations occur through natural processes which by chance, produce advantageous changes. WebLong-term evolution studies are selection experiments that explore evolutionary consequences. Rather than focusing on the potential for selection to act, which is typical of short-term selection studies, long-term studies emphasize the process and eventual outcome of evolution.
