READ THIS This video is NOT meant to be an accurate representation of evolution, as evolution does not have a predetermined goal (though there is the goal to reproduce). This video is meant to test one simple point, that
RANDOM MUTATION + NON-RANDOM SELECTION = VERY IMPROBABLE RESULT.
For further discussion on the use of a "goal" see below. For simulations that represent evolution more accurately see my later videos.
In this video I show why the central tenet of Intelligent Design or ID is wrong. They argue they can tell when an object is "designed", meaning it could not have arisen by chance, but their logic is fatally flawed. Here I will actually simulate evolution showing how impossibly improbable outcomes can appear quite easily, without anything being designed.
For those who fail to find solace in the fact that I have used a "goal" image in this video I will 1) offer a quaint explanation for how this DOES NOT impose design and 2) direct you to Part II of this video.
See, imagine there is an ecosystem where two species live in a symbiotic relationship. Species A offers food to species B for protection. The way species A recognizes species B is because B looks like SouthPark characters.
Now species C happens to also live in this environment but looks nothing like SouthPark characters. They resemble random noise. They go about collecting their food on their own. Evolution by natural selection and common sense tells us that any member of species C that has an advantage in collecting food will be better off (more energy and time for reproduction). Thus that advantage will be passed on.
Therefore, random mutations in species C's population that make members very slightly resemble SouthPark characters will be passed on because those organisms might be able to trick a member of species A every now and then more so than those that are just random noise. As mutations build up in the population of species C, they begin to resemble SouthPark characters more and more, thus tricking species A more and more getting free food and increasing their fitness.
Mimicry like this happens all the time in nature. The evolution of species C is not designed or directed. It just happens that those that resemble species B more (thus looking like a SouthPark character) will have a higher fitness. It is a product of their environment. They will pass on those mutations and the population will evolve.
