1.8Summary

  • Life science took many years to reach its modern form, but produced many accomplishments during its development. Above all, the discovery of cells, Darwin's propounding of the concept of evolution, and genetic research have become the foundations of modern life science.
  • The definition of living organisms includes that they are formed from cells, self-replicate by DNA, respond to stimuli from the environment, and synthesize energy which they use for living.
  • Living organisms on the earth evolved from one species of primitive life form in primeval times.
  • Humans originated in Africa 6,000,000 years ago.
  • Scientific thinking is the foundation of life science and is characterized in that the object of observation should be clearly defined, the data obtained from experimental observation should be debated, objective methods should be used, hypotheses must be tested, and the possibility of correction of errors must be realized.
