Document Summary

Biology = the science of how life works (cognition, behaviour, biomechanics, and physiology) Observation = the act of viewing the world around us. Experimentation = a disciplined and controlled way of asking and answering questions in an unbiased manner. Illustrates how we can piece together individual observations to construct a working hypothesis. Discussed pigeon breeding, fossils, embryology, unusual animals and plants found on islands, etc. Noted success in selecting specific individuals for breeding therefore generating new breeds for agriculture and show. Argued that life has evolved over time by means of natural selection. A hypothesis makes prediction that can be tested by observation and experiments . A single observation or experiment can lead us to reject a hypothesis, or it can support the hypothesis, but it cannot prove that a hypothesis is correct . Researcher sets up several groups to be tested, keeping conditions and setup consistent for all groups.
