Crabs aren’t the only things evolution continues to do. An expert explains.

Charles Darwin believed that evolution created “the most beautiful infinite forms”. It’s a nice feeling, but it doesn’t explain why evolution keeps making crabs. Scientists have long wondered if there are limits to what evolution can do or if Darwin had the right idea. The truth may lie somewhere in between. While there doesn’t appear …

Prior infection and vaccination protect against severe consequences of SARS-CoV-2 infection Omicron

Leave a Comment / Genetics / By admin

A new study published in The Journal of Infectious Diseases reports that prior infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and booster vaccination protect against intensive care unit (ICU) admission and mortality following infection with the SARS variant -CoV-2 Omicron. However, the scope of this protection is reduced against the Omicron variant compared …

Summary: The fossil of a tiny 525-million-year-old sea creature with a preserved nervous system could resolve an age-old debate about arthropod brain evolution. Source: University of Arizona Fossils of a tiny sea creature that died more than half a billion years ago could force a science textbook to rewrite brain evolution. A study published in …

Human evolution was not just a score, but how it was played: Research | Health

Leave a Comment / Genetics / By admin

A group of human DNA sequences that appear to have evolved rapidly after our family line split from that of chimpanzees, but before our split from Neanderthals, have been discovered by a team of Duke scientists. These sequences are thought to be responsible for changes in brain development, digestion and immunity. Compared to our monkey …

Scientists study the evolutionary origin of SARS-CoV-2 using recombination-sensitive phylogenetic analysis

Leave a Comment / Genetics / By admin

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and severe acute respiratory syndrome coronavirus (SARS-CoV) belong to the subgenus Sarbecovirus, which has a genomic length of approximately 30,000 base pairs. These viruses encode four structural proteins, namely spike (S), envelope (E), membrane (M), and nucleocapsid (N). Study: Recombination-aware phylogenetic analysis sheds light on the evolutionary origin …
