What is Meant by "Scientific Evidence" for Common Descent?
Scientific theories are validated by empirical testing against physical observations. Theories are not judged simply by their logical compatibility with the available data. Independent empirical testability is the hallmark of science—in science, an explanation must not only be compatible with the observed data, it must also be testable.
By "testable" we mean that the hypothesis makes predictions about what observable evidence would be consistent and what
would be incompatible with the hypothesis. Simple
compatibility, in itself, is insufficient as scientific evidence, because all physical observations are consistent with an infinite number of
unscientific conjectures. Furthermore, a scientific explanation
must make risky predictions— the
predictions should be necessary if the theory is correct, and few other theories should make the same necessary predictions.
What a
humongous cop-out
Scientific evidence is put in parenthesis
It states that empirical testability is the hallmark of science, then proceeds to break that statement down.
It starts by changing the definition of testability and talks about making predictions.........
And you really really clever guys eat this up for breakfast........
