Fighting the Coronavirus Must Accept Evolution – News

Earlier this year, Dido Harding, while leading the UK’s coronavirus testing and tracking system, said: No one could have predicted a new variant of SARS-CoV-2, The virus that causes covid-19 appears.Of course, this is expected, and some people Questioned Harding’s statementIt seems that many people are still surprised that the virus continues to mutate.

Using covid-19, we took a predominantly reactive approach to new variants. Each time it appears, it attempts to assess genomic changes and see if that means it represents a greater health threat. However, it is important to start taking into account evolution as well as genetic alterations, especially given the recent announcement that cases may be reached. With 100,000 open per day in the UK, new variants may emerge...

In long-lived organisms such as humans, individual gene mutations tend to have little effect. But in a virus, even a single mutation can dramatically affect its fitness-how well it adapts to the host species.This is the reason Fast-evolving viruses such as influenza are always ahead of the best efforts to vaccinate...

The relationship between the genetic composition of an organism and its environment is Modern synthesis of evolutionary biology.. According to modern synthesis, random genomic changes that increase fitness in a given environment are inevitably more common.

Modern theory of evolution takes a similar approach.For example, in behavioral ecology, researchers employ what is known as Phenotypic gambit.. This concept derives from the chess strategy of sacrificing pieces for tactical gain, where genetic changes dominate phenotypic changes, which are measurable features such as eye and hair color. Is assumed. But Gambit stops there. We sacrifice knowledge of certain genetic alterations and instead focus only on observable features when talking about fitness.

Rather than trying to use evolution to predict how SARS-CoV-2 may alter behavior, many researchers have focused primarily on genetic alterations. Geneticists seem to be making their own sacrifices simply by tracking changes in molecular composition. This can be called the genotype gambit.

The sacrifice here is to abandon this reasoning when talking about the risk of variants. That reasoning suggests that more variants will emerge that improve the infectivity of the virus among humans. At least it is not yet possible to predict accurate genetic changes, but we must assume that they will occur and plan accordingly.

Genotyped gambit keeps us on the defensive. For example, the outbreak of covid-19 in mink, Denmark would not have been surprising to evolutionists. Mink-specific mutation.. Certain genetic changes are important, but they are like explanations of the actions we can and should plan – rewritten in the language of genetics.

As the UK lifts the covid-19 restriction, more suitable variants may be found that claim that the virus will be able to evade vaccination. Genome data tells us exactly how this happens, but it is not needed to make predictions of overall evolution.

For example, in the United States, the first and second mRNA vaccinations last for 3 weeks, not the 12 weeks that were first used in the United Kingdom. As a result, the Delta variant took longer to build a foothold there. This can be predicted from the theory of evolution.

The Covid-19 has a long way to go before it comes under control. The data collected on ongoing genetic changes, coupled with Darwin’s theory of evolution, should signal the timing of booster shots and local blockades. But as we continue to play genotyped gambits, the virus continues to defeat us.
