Can you define micro-evolution?

Can you define macro-evolution?

Can you?

Do you want to discuss those definitions* and see where you agree\disagree and why?

Please define macro-evolution for me and maybe we can take it from there?

Even that minor amount of research is completely unecessary. RAZD presented definitions for both micro and macro-evolution right before asking Big Al for his definitions.

Ok...can you tell me what his definition was then?

Re: Definitions - macro, micro, are they different?
Which one is it? And why would you need a definition from me when you have so many available to yourself?

Note that both these types of speciation have been observed in the natural world as well as in the fossil record.

Just to clarify can you give me an example of this in the natural world? And furthermore, if it has been observed in the natural world does that mean it must be true?

Re: So, Big_Al35, what is MACROevolution?
Still waiting for that "observed" example or at least a definition of what you mean by observed.

Percy writes:

we have only directly observed macroevolution in very short-lived species, such as bacteria, fruit flies

Surely, macro-evolution in bacteria should be referred to as micro-evolution by its very nature?

You might want to check out this link regarding fruit flies ---> http://www.icr.org/article/2602/

Re: So, Big_Al35, what is MACROevolution?
Percy writes:

"Micro" is a modifier of "evolution", not of "bacteria". "Micro" refers to the degree of evolutionary change, not to the size of the organism. Bacteria can experience a macroevolutionary degree of change.

All references to evolution on bacteria are referred to as micro not macro. A simple google search will tell you that. Here is one example
http://evolution.berkeley.edu/...ary/article/_0/evoscales_03

Percy writes:

But you seem to be arguing away from the topic. The question is the difference between micro and macroevolution. You seem to want to argue whether macroevolution ever happens.

Well there is no point in defining macro-evolution if it doesn't happen.

A simple Google search of "bacteria macroevolution" returns 148,000 results, and of "bacteria speciation" returns 740,000 results. Perhaps you had a typo when you tried it?

Sorry, no typos. Here is another example which illustrates my point that even articles discussing macroevolution in bacteria are unsure about the definition and indicate that it might just aswell be called microevolution.

Do you have anything to say about the definition of macroevolution?

Yes....I will say this: The pursuit of a definition for macroevolution is a waste of my time.
