Got to have heart

Part of a message thread on the subject of "large-scale" vs. "small-scale" changes.

A fellow named Mike Sims joined the Debunk Creation mailing list, and asked some of the same tired, old questions tossed out by creationists out to disprove evolution. One difference between Sims and the more rabid creationists: Sims listened to and responded to the answers he was given.

• I ask for clarification on the difference between "large scale" and "small scale". In particular, if we can build a heart from nothing in a series of small steps, is that "large scale" or "small scale"?
• Mike Suttkus, listing classes of organisms that fit examples given in original message.
