Provide a summary of biologist Stephen Stearns’ findings in how Natural Selection may be working today in humans.
polet [3.4K]

Answer:

Stephen Stearns states that natural selection doesn't mean the survival of the fittest organisms, but rather this mechanism is illustrated by the selective reproduction of the fittest. Natural selection can be classified into distinct types, including directional, disruptive and stabilizing selection, which are in turn based on sexual selection. These types of selection are driven by different outcomes that have different dynamics.

a culture of e. coli is irradiated with uv light. the highest frequency of mutations would be obtained if after the irradiation,
Klio2033 [76]

Oftentimes UV light can cause the genetic code of an organism to mutate, leading to a variety of errors, some of which are not compatible with life.

UV light is considered to be a mutagen. What this means is that the exposure of cells to UV light often leads directly to a mutation in the genetic code of that cell. This correlation has been studied extensively and shown to affect the nucleotides of DNA, which are:

  • A base (adenine)
  • T base (thymine)
  • G base (guanine)
  • C base (cytosine)

The exposure to UV light causes the base nucleotides in the DNA of an organism to oxidize. This oxidization causes the base pairs to form dimers. Most often the dimer formed is of a <u>thymine base</u>. This can be thought of as the fusion between two thymine bases, which will alter the frame in which DNA is read and <u>cause all sorts of abnormalities</u>.
