One of the factor is the Sun's elevation where the UV reaches us at a much lower frequency when the sun is more distant. Next is our ozone, with our ozone depleting as time goes by, the amount of solar energy it can diffuse is much lesser thus the heat is much more than the previous decades.
Deletion- the fact that a codon is missing implies that the nucleotides were deleted.

Standard taxonomic system is important to the scientific community because it provide several advantages like that organise and classify the organism that organism can be easily categorised it helps to understand the characteristics of a specific organisms, it also benefited to universal recognition that scientific names are standardised and it is accepted universally and it also help to understand the similarities and differences between different species that belonging to the same genera.
(Drawbacks of modern taxonomy) :it is based on physical traits and it is also physically similar and species may not be related and it does not use molecular evidence
