Evidence of Change
Reading practice for pages 10–12. Five relevant words are highlighted.
English reading
During transcription, a cell copies genetic information into RNA. Over generations, natural-selection can favor useful variations, and isolated populations may undergo speciation. These biological processes differ from combustion, a chemical reaction involving oxygen, and from a simple reduction in population size.
