The Big Bang Theory: The Theory Of Evolution
Although nothing is known how it occurred or what existed before hand, if anything at all, the Big Bang was a giant burst of expanding energy, which is still continuously expanding to this day. The Big Bang is estimated to have occurred roughly 13.7 billion year ago. The remains of energy emitted from the Big Bang were able to be observed in the 1960’s and this lead to the theory to become more widely accepted as it could actually be observed. The radiation was discovered by accident by radio astronomers who thought it was nothing but background noise.
The energy levels caused by the Big Bang were astronomical and it took 380,000 years for the universe to cool enough for atoms to be able to form. Before that the universe only contained primitive particles, and later only protons, neurons, electrons and neutrinos. One billion years after the Big Bang stars and galaxies began to form. As the universe keeps on cooling, it continues expanding. It is still currently expanding further and …show more content…
This process occurs due to natural selection. Natural selection depends on the idea of survival of the fittest. Those organisms with the most desired and beneficial characteristics will survive and be able to reproduce, in comparison to organisms with less beneficial characteristics who will not survive in order to reproduce and whose genetic line will die out. This very simple process is what has allowed the thousands of different organisms present today to appear on our planet, all of whose characteristics play some sort of role in the insurance of their survival and reproduction. Charles Darwin was one of the first to observe this process. Darwin was able to study the finches on the different islands of the Galapagos Islands and noticed that they seemed to vary greatly when it came to features such as their beak size and shape. Through studying these finches he was able to observe how each of these different kinds of beaks were able to provide different functions when it came to what the finches were eating. Some proved more useful for eating insects, others seeds, others berries. Darwin realised that these finches were able to develop such distinct characteristics due to the fact that these islands were so isolated from one another and there on their individual islands the finches were able to
