We are all mutants

Mutation of genes, as scientists believe, is the engine of the evolution of all living things. Their cause is errors in DNA processing at the cellular level.

The poisonous chromosome

The short life of men was associated with the "toxic" effect of the Y chromosome. However, so far biologists have studied this only by the example of fruit flies.
