Microorganisms—bacteria, viruses and other tiny life forms—may drive biological variation in visible life as much, if not ...

Enzymes can be used to remove glow in the dark genes from jellyfish DNA which can then be inserted into another organism’s DNA, namely a cat. The potential use of the technology is then ...

Microbes profoundly impact evolution, shaping traits alongside genes. Holobiont biology highlights how hosts and microbes ...

The first type assumes that the rate varies over time and among organisms, but that this variation occurs around an average value. The second type allows the evolutionary rate to "evolve" over ...

The changes and variations in genetic code that occur over time are referred to as "molecular evolution." The molecular evolution of an organism can be very different from its morphological (body ...

How organisms come to vary is the starting point for the study of natural selection, because without variation, there is nothing to select. Lewontin's best known work in population genetics ...
