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 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 ...
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 ...
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 ...
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 ...
In biological evolution, we know that it’s all about the survival of the fittest: organisms that develop genetic traits that allow them to better adapt to their physical environment are more likely to ...
Mitochondria are known as the body’s “energy factories,” and their function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system ...
People calling for early release from lockdown must not ­fully ­understand what we are ­dealing with. The ­coronavirus has a weapon that can always beat us – mutations and throwing up ...
