Not sure if this is the right place to post this but...How do you define the complexity of an organism?One evidence of the occurrence of macroevolution is the fossil record observation that invertebrates were on the earth much longer than vertebrates. Thus showing that "complex" organisms evolved from "simple" organisms. But how do you define a complex organism? Having more cells? Having a skeletal structure? Is it possible to say that an organism with a skeletal structure is "more complex" than an organism without it and why?Edited by Malangyar, : No reason given.Edited by Malangyar, : No reason given.

Are you sure this is true, I mean I'm looking at a wikipedia article right now saying "More complex organisms such as...". I mean can't you say that a multicellular organism is more complex than a single-celled organism?

That it has more parts and thus has a more interconnected whole than an organism with fewer cells.

So what should you use instead? That organisms aren't more complex than others, just different from others?

How do you define complexity then, RAZD? Dr Adequate doesn't seem to acknowledge such a thing, so what's your definition.Edited by Malangyar, : No reason given.
