Ferns, defined by large genomes, high chromosome counts, and pervasive aneuploidy as well as intraspecific polyploid complexity, diverge significantly from the classical genetic theories and ...

The human gastrointestinal tract is in a constant state of flux; it hosts a diverse and dynamic community of microbes known as the gut microbiome, and is constantly exposed to things in the ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

The genome structure — how genes are organized within DNA sequences in an organism — is fundamental to the processes and functions of organisms. A team at the University of Tokyo has developed a ...

A bizarre and ugly fish that has been around for hundreds of millions of years has been discovered to have the most DNA of any animal ever found. These South American lungfish (Lepidosiren paradoxa) ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

The evolutionary success of our species may have hinged on minute changes to our brain biochemistry after we diverged from the lineage leading to Neanderthals and Denisovans about half a million years ...

A 5,500-year-old skeleton from Colombia has revealed the oldest known genome of the bacterium linked to syphilis and related ...
