The Scientific Method For centuries, people based their beliefs on their interpretations of what they saw going on in the world around them without testing their ideas to determine the validity of these theories in other words, they didnt use the scientific method to arrive at answers to their questions. Rather, their conclusions were based on untested observations. Among these ideas, since at least the time of Aristotle (4th Century BC), people (including scientists) believed that simple living organisms could come into being by spontaneous generation. This was the idea that non-living objects can give rise to living organisms. It was common knowledge that simple organisms like worms, beetles, frogs, amd salamanders could come from dust, mud, etc., and food left out, quickly swarmed with life. For example: Observation: Every year in the spring, the Nile River flooded areas of Egypt along the river, leaving behind nutrient-rich mud that enabled the people to grow that years crop of food. However, along with the muddy soil, large numbers of frogs appeared that werent around in drier times. Conclusion: It was perfectly obvious to people back then that muddy soil gave rise to the frogs. Observation: In many parts of Europe, medieval … Continue reading →

Researchers have looked at a species of fish to help unravel one of the biggest mysteries in evolutionary biology. In many species of plants and animals, individuals from the same population often come in different color variants. But the mystery has remained as to why one color doesn't eventually replace the other through natural selection. Research published in the Journal of Evolutionary Biology has looked at a species of Central American freshwater fish to look at how different colors are maintained in the species. Lead researcher, Will Sowersby, a PhD student at Monash University, said the reasons why different color morphs (color variants) existed in a population -- when in theory they should be equally subjected to natural selection -- was still a major question for evolutionary biologists and remained unknown for many species. "The importance of this work lies in the fundamental question: how and why do variants of the same animal exist in nature," he said. "Color variants of the same species are a striking example of biological variation, yet the adaptive significance and what evolutionary processes maintain them, remains unknown." Sowersby said the team looked at a species of fish called the red devil cichlid, which comes … Continue reading →
