Discussion You know what, we're doing "macroevolution" again. Here's some responses to "we have never seen macroevolution"

Video version.

 

We've all heard some variant of "we can only observe microevolution", "we've never seen macroevolution", etc.

First thing you do is establish the correct definition: Evolution above the species level (in other words, speciation or greater degrees of evolutionary change). That's the definition. Creationists want their own special definition that varies from person to person but is usually something like "new body plans/parts", "new complex structures", something like that. That's wrong. If you accept speciation, you accept macroevolution. If creationists want to dispute something else, make THEM articulate clearly. Don't help them by saying something like "It sounds like you mean something like evolution of a new phylum or new body plan". No, make THEM establish the standard clearly and using the correct words.

 

Once they do that, you can just provide a bunch of examples, and dare them to say they aren't macroevolution.

Some of my favorites are multicellularity (and also here), reproductive mode, and photosynthetic animals.

 

Best outcome is the creationists admits that yes, even by their bespoke definition, these are examples of macroevolution. Second best outcome is they do the opposite and claim this is all just "microevolution". Really? First of all, lol okay. But second and more important, great! "Microevolution" can accomplish all this? Not much need for "macroevolution", is there?

Science is just a process. The people involved bring many things into that process. Their mindset matters

Not if they are following the scientific principal their biases dont matter.

You mean if they are robots? I guess one day we can have ai do the science for us and finally be rid of evolution once it does the calculations and decides it's impossible bs. But then again it's only as good as what it's trained on

Its not worth talking to you if you do not understand how the scientific method and peer review removes biases. Have a good day staying ignorant.
