What Do These Photos Mean?

     Using Survival of the Sickest and Your Inner Fish, we have to describe the following two photos.

     This flower has most likely developed its colors for more reasons than one. If I had to take an educated guess, I would say that it developed bright colors to attract bees, so that it can be pollinated. Another possibility is that its colors act as a warning sign, causing less animals to eat this flower for fear of being poisoned. It discussed something like this in Chapter 4 of Survival of the Sickest, when is said that when plants containing phytoestrogens are consumed by animals, the estrogen-like compound affects the reproduction of these animals, reducing the number of animals that eat that plant. 

Rewriting what I wrote in the previous blog post, "Failure of “Sonic hedgehog” to turn on properly can result in extra fingers, paddle hands. Similarly, malfunctioning ZPA results in malformation in hands". This is different than what the scientist in Chapter 3 of Your Inner Fish were doing. What the scientist were doing was moving the ZPA patch from one side of the bud, which in later development is the hand, to the other side, resulting in an exact duplication of the fingers, not like what is seen above, but rather what is seen below.

     Notice that in the experiments done in this chapter, the two ends of the arm where mirror images of each other.
