BIOL1001 Lecture Notes - Lecture 1: Koala, The Mammals, Stromatolite
Document Summary
Biology is a natural science concerned with the study of life and living organisms. Modern biology is a vast and eclectic field composed of many specialized disciplines that study the structure, function, growth, distribution, evolution, or other features of living organisms. A collection of organisms clockwise from top left: bacteria, koala, fern, toadstool, tree frog, tarantula. Biological research indicates the first forms of life on. Earth were microorganisms that existed for billions of years before the evolution of larger organisms. The mammals, birds, and flowers so familiar to us are all relatively recent, originating within the last 200 million years. Modern-appearing humans, homo sapiens, are a relatively new species, having inhabited this planet for only the last 200,000 years. Stromatolites, sedimentary accretions formed by the actions of cyanobacteria, provide fossil evidence of life on. Although modern biology is a relatively recent development, sciences related to and included within it have been studied since ancient times.
