What animals can survive climate change?

For years there has been concern about climate change and how it may affect some endangered animal species. A new study in Canada has asked the question “Which animals will survive climate change?” focusing mostly on a marine species and they seem to have found a rather surprising answer What animals will survive climate change? Researchers at McGill University in Canada, using genome sequencing, have shown how some fish, such as the spiny, can adapt very rapidly to extreme seasonal changes. Studies on this particular specimen will be able to help scientists predict the evolutionary future of these populations, thanks to its extraordinary abilities, which make it capable of living in both fresh and salt water and in a wide range range of temperatures, depending on the conditions of the habitat in which they are found. The objective of the research was to understand the sequence of events that led to the adaptation of this particular species, following Darwin’s theory that “organisms with genes that promote survival and reproduction will tend to leave more offspring than their peers, causing an increase in the frequency of genes over generations. “To study this natural selection in action, the researchers monitored the prickly pear before and after seasonal changes in its natural environment, sequencing its genome. The alternation of wet winters and dry summers has caused drastic changes in the habitat and chemical balance of the water, selecting only those fish that can tolerate such a rapid change in the environment.Surprisingly, the researchers found evidence of genetic changes in thorny trees that have adapted due to changes in the ecosystem and that have also occurred in independent populations over the course of a single season, highlighting the speed with which the effects can be detected. Natural selection. The findings are important because they suggest that we can use genetic differences that have evolved in the past as a method to predict how populations might adapt in the future to environmental stressors such as climate change. In this sense, the scientists They do not rule out the analysis of other animal species that have changed their genetics in the relatively near past to analyze if they are doing it again to adapt to the current situation with respect to climate change.
