The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...
The study of the genomes of our closest relatives, the Neanderthals and Denisovans, has opened up new research paths that can broaden our understanding of the evolutionary history of Homo sapiens. A ...
Recently, a paper entitled “Genome-wide DNA methylation landscape of four Chinese populations and epigenetic variation linked to Tibetan high-altitude adaptation” was published online in the journal ...
Twenty years ago last month, scientists sequenced the first human genome in the landmark Human Genome Project. Among the many things they discovered was that while any two humans have 99.6 percent of ...
A new study explores 'balancing selection' by analyzing thousands of modern human genomes alongside ancient hominin groups, such as Neanderthal and Denisovan genomes. The research has 'implications ...
We learn that we inherit two copies of every gene, one from each of our parents, but the story is a bit more complex. Some parts of the genome may be duplicated, or deleted, in some people. The number ...
Stephen Shore, an autistic professor of special education at Adelphi University, has said: “If you’ve met one person with autism, you’ve met one person with autism.” This quote is popular in the ...
Cluster headaches, anxiety and depression can be debilitating for people living with these conditions. Psychedelic drugs have shown benefits as treatments for these conditions in clinical studies, but ...
One in 100 people have genetic variations that can cause potentially life-threatening heart conditions, including high cholesterol (lipid disorders), heart muscle disease (cardiomyopathies), and ...
