Could you be more wrong? One can infer bit not observe natural selection. One CAN observe the change in DNA of populations and that is by definition, is evolution.
Evolution, ie change, is the observed fact. The theory of natural selection helps to explain and predict this fact.
“Could you be more wrong? One can infer bit [sic] not observe natural selection.”
Could you? Berkeley:
“In some cases, we can directly observe natural selection.” http://evolution.berkeley.edu/evolibrary/article/evo_26
“The central idea of biological evolution is that all life on Earth shares a common ancestor, just as you and your cousins share a common grandmother.”
http://evolution.berkeley.edu/evolibrary/article/0_0_0/evo_02
Does an observable phenomena contain a “central idea”? Is the central idea of a common ancestor an observable fact?
If you won’t here it from me, will you here it from a highly credible source that actually teaches evolutionary theory?
I don’t agree with their confidence in common descent, but at least the pages I cite here agree as to the terminology of the debate.
