An important development took place in Darwinism, the theory of evolution, which was added to the scientific world by the British natural historian Charles Darwin, which argues that living things developed through natural selection. Scientists examining genetic diversity have revealed that evolution may be happening four times faster than previously thought.
The new research, published in the journal Science, examined the genetic differences of 19 different groups of wild birds and mammals around the world. The results of the study, which was completed in 3 years, showed that the genetic difference necessary for evolution was much greater than previously estimated.
There is no evidence yet that they evolved faster than in the past:
In their long study, scientists measured how much species variation genetic and natural selection caused. Although this study, which is the first of its kind, points out that species may be evolving faster than in the past, scientists emphasized that there is not enough evidence yet to fully prove this.
The new study had another importance. The changing environmental conditions all over the world with climate change mean that animals also have to adapt to new conditions. According to the scientists, the new study explained that the rate of evolution can affect population dynamics and that natural selection can partially reduce the effects of current change in the environment. A study of how quickly evolution happens may help us to predict in advance which species will adapt to future change, that is, whether they will survive.
