Despite the widespread opinion, the evolution of living organisms nevertheless occurred in completely different ways – not only in different species of the same kingdom, but also in different species in principle. Today, specialists in evolutionary biology from the University of Arizona presented their new study on the evidence found for polyploidy in insects, which is a rather unusual and revolutionary discovery that will allow us to finally understand the differences in the evolutionary process of animals and plants. An article with these research results has already been published in the scientific journal Proceedings of the National Academy of Sciences.
Evolutionary biology is a separate area of biology, the study of which primarily includes studying the mechanisms of genetic development of various living organisms. Already during the last century, several scientists have proved the process of polyploidy – the process of genomic reproduction – in plants, however, studies of that time did not allow it to finally be attached to the animal kingdom.
Now, thanks to a special bioinformatic research system developed by a team from the University of Arizona, the polyploidy process has been discovered in insects, which are the richest department of the animal world in terms of evolutionary biology. The detection of traces of polyploidy was made possible thanks to a new set of methods and techniques for studying genomic duplication – thus, the team was able to detect these traces in some types of insects, which clearly indicates a similar process in other animals.
However, scientists are in no hurry to come to such conclusions so far, as it is necessary to double-check the data obtained from the bioinformatics system in the context of studying other types of insects. However, if in the future this theory is finally confirmed, then evolutionary biology will open up completely new horizons for study and discovery, and some research results will probably find their embodiment in new systems and research methods.
