In the natural selection theory, not a large number of mutant individuals appear at once, the mutation that "happens to the surrounding environment" happened by chance will spread over time throughout ...

BENGALURU: A new scientific paper published by a team of scientists from the National Centre for Biological Sciences (NCBS) in Bengaluru and Western University, Canada, has shown direct evidence for ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

(Memphis, Tenn.—July 28, 2023) The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children’s Research ...

A single genetic mutation may have been responsible for allowing multicellular life – and eventually humans – to evolve on Earth. Biologists have found a lone gene capable of turning single celled ...

Molecular evolutionary biologist Masatoshi Nei says Darwin never proved natural selection is the driving force of evolution — because it isn't. In a cavernous concert hall, before an eager audience of ...

A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...

Mutations, which occur continuously in every cell of our bodies, are a key contributor to cancer, ageing, and neurodegeneration. While exposure to mutagenic chemicals, or mistakes in cellular ...

The analysis revealed that about 2 per cent of sperm from men in their early 30s contained disease-causing mutations. That ...
