• Biology - The study of life.
• • Bios - Life
• Biology - Life and its beginning, it also deals with structures, functions and relationships of organisms with their environment.
• Assigning names (scientifical) - Binomial Nomenclature.
• Divine Creation is a hypothesis stating that life came from a divine being or God.
• Spontaneous Origin hypothesis suggests that life came from inanimate matter, which was a small matter which later became a complex one called "amino acids".
• Panspermia - Argues that life originated In space, in spatial ice, and continuously distributed to the planets by comets and meteorites.
• Miller-Urey Experiment - Provided the first evidence that organic molecules needed for life could be formed from inorganic components.
• • Logos - Study
• Francisco Redi concluded that the maggots were the offspring of flies, and that the presence of maggots in a meat-filled jar had nothing to do with the meat inside.
• John Needham concluded that life originates from non-living things, based on an experiment where boiled broth was kept covered or uncovered.
• Lazzaro Spallanzani concluded that life formed from something that entered the flask through the air and is responsible for life, based on an experiment where boiled broth was kept covered or uncovered.
• Louis Pastur concluded that the concept of biogenesis, which states that a living thing can only come from another living thing, is supported by an experiment where boiled sugar, a swan-necked flask, and yeast were used.
• Louis Pasteur‘s Experiment

  • He boiled some sugar solution with yeast in a swan-necked flask (a flask with a long, curved neck).
  • Although the flask was left open, no organisms developed in the mixture.
  • This was because the microorganisms were trapped on the bottom of the curved neck of the flask, the solution was soon teeming with microorganisms.
  • This was because airbone microorganism were able to enter the flask easily.
  • The result of this experiment supported the concept of biogenesis, which states that a living thing can only come from another living thing.
