How we created the 'perfect storm' for pandemics

The way that many of us live has created the "perfect storm" for the evolution and transmission of infectious diseases like COVID-19 according to a researcher at the University of East Anglia.

A new perspective on the genomes of archaic humans

A genome by itself is like a recipe without a chef—full of important information, but in need of interpretation. So, even though we have sequenced genomes of our nearest extinct relatives—the Neanderthals and the Denisovans—there ...

Ancient fish DNA provides a window back in time

The accidental discovery of fossilized three-spine stickleback bones dating back 12 thousand years, has enabled scientist to confirm parallel evolution, or evolutionary changes or adaptions which take place repeatedly.

The trouble of being tall: Giraffes and their genes

The giraffe is a truly puzzling animal. With its exceptional anatomy and suite of evolutionary adaptations, the giraffe is an outstanding case of animal evolution and physiology. Now, an international team of researchers ...

Gene discovery may help peaches tolerate climate stress

A Boyce Thompson Institute-led team has identified genes enabling peaches and their wild relatives to tolerate stressful conditions—findings that could help the domesticated peach adapt to climate change.

'PopDel' detects deletions in our genomes

The human genome contains roughly three million letters and is distributed over 46 chromosomes. Yet the genetic variation from person to person is very small: the genome sequences of any two people differ from each other ...

New mutations and proteins of novel coronavirus revealed

A recent study from the Indian Institute of Science (IISc), published in the Journal of Proteome Research, has identified multiple mutations and unique proteins in isolates of SARS-CoV-2, the virus that causes COVID-19. It ...

Genetic variation

Genetic variation, variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the “raw material” for natural selection.
