Struggled with this earlier but because of the high altitude only some animals can live there and thrive because of the lower oxygen levels
Radiation can damage DNA. This could result in a change in the proteins which make up the plant's physical structure.
<span>For example, a plant might have a gene for purple pigment which makes its flowers purple. Radiation might change the DNA sequence so that the directions for making the purple pigment tell it to stop prematurely, and the result might be white flowers rather than purple flowers.</span>
A reduction in volcanic activity and earthquakes. Which results in causing warmer surface temperatures because particles released by volcanoes have a cooling effect.
