Cilia Is An Irreducibly Complex System

Decent Essays
Irreducible Complexity is an idea sparked debates with scientists for generations. This is the notion that a complex part of an organism could not have evolved over a long period of time since it would not have contained all the key components to keep it functioning. Darwin himself knew that his theory of evolution was hanging by a thread when he said, “If it could be demonstrated that any complex organism existed that could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.” One of these irreducible complex organisms is Cilia. Cilia are hair like structures that are usually used to move structures around inside of an organism within liquids. The cilia are consequently able…show more content…
We could not just have the microtubules for they cannot not bend, it would not make any sense to have “bridges” because the microtubules would still not bend, and if we only had the arms that move the microtubules they would just break apart from each other because there were no bonding “bridges”. As we can see, the cilia are an irreducibly complex system.
Another irreducibly complex system is the eye. The eye is a complex system made up of multiple different functions. The eye consists of Cornea, the Iris, the lens, the Retina, and Optic Nerve. The Cornea is a tough outer shell around the outside of the eye. This refracts light as it enters the eye. The Iris controls how much light enters the pupil. The Lens focuses light into the retina. The Retina is where the light receptors are. The Optic Nerve sends the images back to the brain where they form an image.
So, as you can see, every one of these functions is needed to complete a functioning eye. It would be hard to see how the eye could have done its job effectively if it evolved slowly over time. Each one of these parts is very fragile and even the smallest altercation could destroy all
