    Hi Maddy,
    I love the creativity and visual representation of negative frequency dependent selection. I think you did a really good job using the side blotched lizards as a guide to how this phenomenon works. I think one of the biggest factors within negative frequency dependence is the sexual selection preference changing due to the more frequent characteristics!

    Maddy,
    Wow! I love the creativity and work you put into making the video. This definitely helped me better understand what we modeled in the last R studio assignment. I like how in this example you used territory as a factor. In frequency-dependent selection, I kept thinking of how a variety of colors would impact the selection. When the orange was spread out over a large area, it made it easier for the yellow to come in and take over. From your research, were you able to determine if this cycle ever stops? From our graphs in class, it looks as if the process repeats itself over and over, but I was wondering if you learned of any other variables or events that prevent the cycle of colors taking over as most frequent in the population.

Microphis deocata

  In most species, the male is usually more elaborate while the female is more drab and picky about her mate. This is often because the females are the ones that put more energy into offspring both by producing the egg and in parental care. Microphis deocata  are the opposite. The female is more elaborate while the male is more drab and picky about his mate. This could suggest that the male provides more parental care to the young than the female. Pipefish  biology supports this hypothesis because the males have a brood pouch. After the male fertilizes the eggs, the female deposits them into the male's pouch where they remain until they hatch about 15 days later.  Sound familiar? Seahorses are very similar with the male carrying the eggs in a pouch, a trait that possibly evolved in a common ancestor since both seahorses and Microphis deocata are part of the Syngnathidae family. However, unlike in pipefish where the eggs are fertilized in the female, in seahorses, the...

What is Evolution? Fact or Theory?

Image
         Evolution can be explained in many ways. I remember my 8th-grade science teacher telling us to think of evolution as starting with a single microscopic organism that was the first living thing on earth and that over time it changed and evolved to become more complex and branched out into several different species and this continued giving us the greatly diverse life forms that we have today. A couple years ago I took a Vertebrate Zoology course and my professor had a different way of explaining what evolution was. He explained evolution as how animals adapt to their changing environment. So for me, evolution is a combination of those two ideas. I explain evolution as how living organisms adapt to a changing environment over generations and how these adaptations can lead to the formation of new subspecies.      I think that evolution can be both a fact and a theory depending on the context. In terms of bacteria becoming resistant to a...
