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

In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of
Reika [66]

Answer:

Explanation:

The rate of pollination in the field (near the pond with no fish) will decrease exponentially. Because, as the fish population is removed from that ecosystem, the population of dragonflies and larva increases without check because, fish feeds on the dragonflies larva and kept there population in check. Due to this, the population of bees and other pollinators population decline becuase, they are major food source of dragonflies.

Honeybees are the keystone species because it's absence will lead to major changes in the ecosystem.
