Your Inner Fish: Arms Deep in Evolutionary Change
Your Inner Fish by Neil Shubin is the closest thing humanity has to prove The Theory of Evolution. Creationists’ have yet to accept fact, but that’s for another essay. Although this book is a specific collection of evidence, this wasn’t the first time the idea of creationism was challenged. This book is one, rather simple, explanation of what our lives truly are: a product of millions of years of evolutionary change. As Shubin states in his book, fossils are found based on two polar opposite things: serendipity and fact based knowledge. He states that 99% of organisms that have ever lived on earth are extinct and that we will never know they even existed because only a miniscule percent …show more content…
Tiktaalik shows us how even early tetrapods relate to humans. Tiktaalik is nearly perfectly for proving his theory about the transitions between organisms, in this case, fish and amphibians. It has a scales and fins with webbing, but the fins contain the standard limb structure of one bone, two bones, lots of bones, digits. It also has a flattened head and even the neck of a tetrapod. It has a limb structure that is just like humans, cats, rats, and everything else.
What is interesting is that Tiktaalik has the arm and muscle structure to do ‘push-ups’. Oddly enough, when you consider its environment and its predators and prey in that time period, it’s extremely useful. The flat body with eyes on top of the head and the powerful limbs allowed it to lift its body through marsh and out of the water. There were massive predators in the area and the ability to move to where predators couldn’t move into was handy, to say the least. Pun intended.
If there is one rudimentary principle in biology it is this: every living organism on this earth had parents. Even more basic, every living thing is more or less different from their parents. This is true even if you go back to the chemical reactions that are the primogenitors for organic molecules that are the precursor for living things. In this way, there is no difference between: mom + dad = baby and 6CO2 + 6H2O → C6H12O6 +
