The Darwinian Evolution tells us about the struggles that scientists faced in the past, as well as some struggles that are still being faced in the present. Charles Darwin was on the Beagle expedition, which landed at the Galápagos Islands. Here, he was able to observe many new species which people had never seen back in England. It was on these islands where he made observations and formed a theory of evolution that would forever revolutionize the way we see creatures, as well as ourselves.

While on the islands, Darwin observed many different kinds of finches. He noticed that depending on which island the birds were located on, they shared different characteristics. Some finches had thick, shorter beaks, which would have been used to eat nuts and other large, harder foods. On other islands, he observed finches with smaller beaks, used for eating seeds and smaller foods that were located only on that island. From these observations, as well as the data he collected from many other creatures, Darwin concluded that these finches must have all shared a common ancestor. He believed that there was an original species of finch that started living on the island. Some finches made their way to other islands, where there were different climates and food sources. The finches that had mutations, such as a smaller beak, would be more adapted to eating the seeds of the new islands, while the other finches with larger beaks would eventually starve.

This brings up the idea of “survival of the fittest”, which suggests that the animals with mutations best suited for their environments would outlive the others of their species. Eventually, only the finches with the smaller beaks would live long enough to produce offspring, and these offspring would share the useful physical traits of their parents. Soon enough, an entirely new species of finch would be found on the island, and the ones with larger beaks would be found on the island where more nuts and large foods were located.

Darwin hypothesized that since these birds evolved from a common ancestor, it could most likely be concluded that even humans had a common ancestor, and eventually evolved into the people that we see today. This idea went against the church, however. The idea of evolution, and not that one god created each creature at the same time, went against religious beliefs of the church, and for this reason Darwin was hesitant as to whether he should publish his findings. He ends up doing so in a book called Origin of Species, and this book would forever change what we believe about species and their ancestors.

Even today, scientists have fears when it comes to publishing their findings, as they may go against what is commonly perceived to be true. Today, scientists must get over their fear of the backlash that they may receive, and publicize their findings so that the general public may become informed as to the research that is being performed. Once the new knowledge is out in the open, it may change our entire perception of the universe, just like Darwin did when he published his findings in the 1800s.
