Biology-Discussion

400 or more words- Due Wednesday 8PM EST
 
 
 
After reading the article “Darwin Lives!  Modern humans are still evolving” are you convinced that humans continuing to evolve?
From what you have learned about adaptation, natural selection, and genetic drift, choose one side of this debate and discuss one clue that humans are either continuing to adapt or have ceased any evolutionary advancement.
Remember, as explained in the lecture, a key to evolution is the passing on of genes.  Evolution through natural selection does not work as “survival of the fittest” but rather, “survival of the genes from the most reproductively fit” (unfortunately, that doesn’t have the same ring to it!)

Biology discussion

I’m stuck on a Biology question and need an explanation.

This week is all about introducing you to the science behind nature. For your primary post, select ONE of the following discussion topics. Using your own words, write a primary post that addresses each question.

Your primary post is worth 24.5 out of 35 points. The remaining points are earned by replying to at least one of your classmates. You don’t need to use any sources other than the ones specified, but if you do use other sources, be sure to cite them.

Topic 1 : Evo-devo. Watch the video (1)* featuring Sean Carroll discussing the science of evolution and the field of evolutionary-developmental biology (evo-devo).

  • (a) Describe three things that you learned from the video.
  • (b) Of the three things you described, which was the most surprising, and why?
  • (c) Share what you feel this teaches you about biology (the study of living organisms).

Topic 2 [article]: The cusp of a revolution in medicine. In a recent op-ed, Craig Venter (2)* shares his opinion that we are “on the cusp of a revolution” in medicine.

  • (a) Describe three things that you learned from this op-ed.
  • (b) Of the three things you describe, which was the most surprising, and why?
  • (c) Share what you feel this teaches you about biology (the study of living organisms).

Topic 3 [article]: Earth will survive; we may not. Astrophysicist Adam Frank says that “pretending we can just extend the Holocene in perpetuity” is just a foolish excuse to put off making inevitable choices brought about by climate change.

  • (a) What did Frank mean by his statement above?
  • (b) Some biologists, particularly conservation biologists reacted negatively to this essay. What is your reaction to this essay?
  • (c) Share what you feel this teaches you about biology (the study of living organisms).
