Less, but more: A new evolutionary scenario marked by massive gene loss and expansion

A new evolutionary framework called “less, but more” extends the previous model in terms of the importance of gene loss as an evolutionary driving force. Gene loss reduces the number of FGF growth factor gene families from eight to two, which then double over evolution to generate a total of ten genes.

Uncovering two rare infectious diseases which might be responsible for COVID-19

A new study suggests that COVID-19 likely emerged from the natural fusion of two rare infectious diseases, glanders and Sennetsu fever, with some common human diseases. DNA methylation patterns at 865,859 CpG sites in blood samples from early COVID-19 patients revealed strong genetic link evidence supporting this theory.
