Document Summary
A coherent set of testable hypotheses that attempt to explain facts about the natural world. Something we use to explain ideas in science. Continually tested and debated known as the scientific process. Theories are not falsifiable (can"t be proven to be false) Allele frequencies in a population change from generation to the next. Vestigial traits(unnecessary trait that has no use) Direct observation od evolution n real time. Examples of homology and why they support the idea of evolution. Similarities between 2 species not explainable by shared function, that reflects shared ancestry. Positioning and functions of arm bones of humans similar to those of turtles, horse, bird, bat and seal. Examples of vestigial traits and why they support the idea of evolution. Vestigial trait is a trait that is not necessary but is part of a species anyway. Support evolution because they suggest that at one time this trait was necessary so only those who had this trait survived to reproduce.
