This is actually a very critical question, and not one to be laughed off. The question is how do you validate what someone is saying to see if it really is true.
Might be a good question for the
History thread. Verification is very important when investigating history.
Example #2 - "Haeckel's Embryos":
And we have a
Recap thread as well. Much more information and discussion can be found there. Another good source would be the "
Lies in the Textbooks" video.
One who evaluates motives based upon actions rather than words can easily figure out the deal on these.
The common claim is (a) that Haeckel's embryo drawing are frauds and (b) that they are still being used to teach evolution, even though evolutionists know they are frauds. This is a little more complex.
Not really. Recap doctrine is presently a part of the religion which is enthusiastically encouraged, but no longer required. Pretty simple.
So you can look at the evidence and see that (a) Haeckel did fake parts of his drawings and (b) they are used to teach an aspect of evolution that is observed in actual embryos today.
And what would this aspect of evolution be?
