(Reuters) - Midfielder Curtis Jones and full back Tino Livramento have been included in England's squad for their Nations League fixtures against Greece and Finland, England's Football Association said on Wednesday.

Advancements in medicine and healthcare mean that humans are able to pass on more and more unwanted genetic mutations to our offspring, resulting in decreased genetic fitness. — dpa

Aiming to better understand the issue and to figure out how worried we should be, scientists in Germany and the United Kingdom have carried out what they said was “the first mutation accumulation experiment on a mammal”., the researchers from the University of Edinburgh and the Max Planck Institute said that each generation sees spontaneous mutations that “introduce heritable changes that tend to reduce fitness in populations of highly-adapted living organisms”.

The team said that while genetic mutations are typically “countered by natural selection”, which ultimately removes most of them from the population, societal changes in recent decades, such as improvements in living conditions and healthcare, have “reduced the strength of natural selection”.
