27
Observation,.............,prediction,......,conclusion. Model. What's missing?
Hypothesis formation and experimentation
28
What tests the hypothesis?
Experiments.
29
A hypothesis is
``` A possible explanation for an observation. Tested to determine validity Tested in different ways Allows for predictions to be made. An iterative process ```
30
Scientific theory is
Body of interconnected concepts. Supported by much experimental evidence and scientific reasoning. Expresses ideas of which we are most certain.
31
What was Darwins contribution to the theory of evolution?
A mechanism- natural selection.
32
Was Darwin the first person to propose evolution?
No . Malthus An essay on the principle of population.populations increase geometrically, food supply increases arithmetic ally.
33
Homologous structures
Same evolutionary origin but differ in structure and function.
34
Analogous structures
Different origins but used for the same purpose | Eg wings of a butterfly and bird.
