Biology is the subject that explains the natural world around us. The number of lifeforms present on earth range in the billions. From the tiniest microscopic microbes to the largest ever animal that ever walked the earth, biology tells us how life came to be on this planet. Nobody knows how life actually started, but there are many different theories that show varying degrees of plausibility. But once the first life forms established itself on earth billions of years ago, evolution kickstarted the diversification of all life. From unicellular organisms capable of producing their own food to predators who preyed on them, the earth was abound with life. In the earth’s 4.5 billion-year-old history, many species came and went. For instance, man is the dominant species on earth today. But 65 million years ago, dinosaurs ruled the earth until they went extinct. Life was even stranger before the dinosaurs – the high levels of oxygen in the atmosphere led to the rise of insects that were 10 times as large as today.
