A letter about the evidence of evolution
GuDViN [60]

Answer:

I am writing this in response to a letter regarding evolution. Evolution is increasingly solid, not shaky. Darwin’s “theory” or explanation was a way of understanding what he had discovered (which did not include genes, chromosomes, DNA or nucleotide bases). Our explanations now include genetics and the commonality of mutation.  

Proofs are solid, not in question by serious scientists. Direct observation is one, which we see in the fact that this year’s flu evolved a little too far from last year’s, so flu shots are less effective this year than we would like them to be.  

Fossils tell the story well: whales with legs, dinosaurs with feathers and Tiktaalik. The latter was found in the Canadian north and is part fish, part amphibian, before there were ever any amphibians. Imperfection is a good proof: think of your useless appendix, the very bad design of your ankles, knees, and back (talk to a chiropractor about that).  You have big toes because they used to be useful thumbs for your grasping feet.

Many other animals and even plants similarly have flaws that show their evolutionary past. Two large human chromosomes reflect the coming together of two chimpanzee chromosomes each.

Hope it helps,

Please mark me as the brainliest

Thank you

Bleaching is caused by the addition of bleach containing fertilizers that enter marine systems through runoff. True False
Natali [406]

The given statement is False

Bleach such as chlorine when mixed in fertilizers acts as a killing agent for plants .The bleach runoff is not affected by the fertilizers containing bleach as they do not kill the Aquatic flora. Marine bleaching is caused due to high temperature of water not because of the fertilizers. In marine bleaching the coral will expel algae when the temperature of water is high. These results in discoloration of corals making them white and they can survive in this condition. This proves that the bleaching inside the marine system is because of high temperature not because of runoff.
