Your Inner Fish Reflection

     For the past week we have watched the documentary "Your Inner Fish" starring Neil Shubin and it went over our inner fish and reptile and how many of our characteristics evolved from them and the physical characteristics which we adapted to own. This series not only taught me about the evolution of man kind but provided insight into my own biology and how fit into the grand scheme of earths history.

     One of the questions asked was "What are some of the forms the descendants of Tiktaalik evolved in their limbs?" This question surprised me because it showed how similar we were to early amphibians and the how their was a transitional fish that filled the evolutionary gaps. Some of the different forms include amphibians, claws of reptiles, arms of primates, and the human hand. This showed how all animals originate from some form of a common ancestor and how only the most vital of adaptations have survived evolution.

     Another question that interested me was "What is significant about the master gene EDA?" Master gene EDA is the gene that controls all of our skin organs such as teeth, hair and feathers. It helped to connect all animals as this gene is present in all species and develops some of our most defining characteristics. It connects to our unit about genes since it shows the regulation of genes and traits, but also about how this gene has survived natural selection and evolution to allow us human beings to evolve.
