Certain species of living things can survive extreme weather changes. This was revealed by a geneticist from the University of British Columbia. Rowan Barrett in Vancouver. Canada. Friday (6/8).

Based on his research, a species of fish is able to survive for three generations from sharp weather changes. The research, conducted with European researchers, was carried out by moving seawater fish into a pond where the water temperature was gradually lowered. As a result, the fish were able to survive for three generations The fish in the last generation were able to survive at a water temperature 2.5 degrees below the water temperature experienced by their great-grandparents Similar conditions are believed to occur in several other species of living things.

However, Barrett warned, the evolutionary leap could lead to large numbers of deaths. As many as 95 percent of the fish used in the study died and only 5 percent survived. It turns out that extreme weather changes do not guarantee the sustainability of living populations and that is catastrophic.

""There are consequences that living things must experience to be able to survive in extreme changing weather conditions,"" he said. However, the researchers have not yet confirmed whether the survival mechanism can be used by creatures living in temperatures that get hotter, not colder, like the fish study. In fact, over the past few decades, global temperatures have risen, bringing alternating changes in extreme hot or cold temperatures. (AFP/MZW)
