The observation of microorganisms appearing spontaneously in broth that was thought to be sterile led to the theory of abiogenesis, the idea that life can arise from non-living matter under certain conditions. This was later disproved by Louis Pasteur's experiments, which showed that life only comes from preexisting life.
The name of the theory that explains Brown's observation is the kinetic molecular theory of matter. This theory states that all matter is composed of particles (atoms or molecules) that are in constant motion, and explains the behavior of gases, including diffusion, pressure, and temperature.
The discovery of genetics and the mechanism of inheritance through Gregor Mendel's work provided evidence supporting Darwin's theory of natural selection. This, along with the fossil record showcasing transitional forms and the observation of adaptation in response to environmental pressures, led many scientists to accept Darwin's theory over earlier ideas like Lamarckism.
Walter Sutton discovered that the traits of an organism are determined by specific factors located on chromosomes, which are passed down through sex cells during reproduction. This observation led to the development of the chromosome theory of inheritance.
The invention of the microscope led to the development of the cell theory. Through the use of microscopes, scientists were able to observe and study cells, leading to the formulation of the cell theory in the 19th century.
Virchow observed that cells can only arise from pre-existing cells, leading him to propose that "Omnis cellula e cellula" (All cells come from cells). This observation supported the idea that cells are the fundamental unit of life, which is a key component of cell theory.
They don't! Abiogenisis is not part of evolution as you need already living organisms to evolve. This is a common creationist misunderstanding of evolution and evolutionary theory
Observation
scientific theory
a theory which is made by observation
theory hypothosis
They never heard of this theory.
Jean Senebier developed his theory of plant respiration after observing that plants consume oxygen and release carbon dioxide during photosynthesis. This led him to propose that plants have a respiratory process that involves the consumption of oxygen.
Novanet: THEORY
If new observations are discovered that clash with the previous theory, then the theory will have to be revised.
An hypothesis is a theory based on observation and the knowledge of the topic.
observation proved the theory true.
