I've been wondering for awhile now if there are any strong theories or propositions other than Evolution, as all I ever see are arguments between Intelligent Design, Creationism, and Evolution. Is anyone familiar enough with alternative ideas that they may name and explain them?

Ha ha.

I'm serious though, are there any other serious theories or propositions that have intellectual merit, or is Evolution the only thing out there?

There is no scientific alternative if that is what you're asking. Although there is some disagreement between evolutionary models of morphological gradualism and punctuated equilibrium.

Also there are numerous different types of creationism (See here: http://en.wikipedia.org...).

There's Lamarckism and stuff. I don't know much about it, as always.

Of course, I don't think it has any scientific support, but it's an alternative scientific theory.

Yeah, I think the lone term "evolution" gives a false sense of security. There is still so much debate within it haha

Gradualism and Punc Eek are not mutually exclusive. The "argument" is over which is more dominant a force when it comes to driving evolution. You can take a large population growing under gradualism and, using massive genetic drift, create what the fossil record reflects as "punctuated equilibrium."

Personally, I think Punk Eek may have more of an edge on gradualism when it comes to increased variation. For instance, gradualism can lead to a stasis species, while each Punk Eek cycle would create noticeable differences.

Panspermia would be an alternative to Abiogenesis, not evolution.

I'm far, far from knowledgable on this stuff but I listened to a Radiolab episode a while back where a biologist was arguing that Lamarckian ideas were making a come back: http://www.radiolab.org...

The idea was that newly discovered mechanisms can effect epigenetic (heritable changes caused by something other than the underlying DNA sequence) alterations. That's not an alternative to evolution, but it has some implications for the mechanisms it works by.

Not quite correct.

Evolution in its most general form is DIFFERENTIAL selection and variation.

It is possible that things like genetic drift, neutral mutation, or even epigenetics play a substantial role in differential selection alongside natural selection.

Hell, I'll give Margulis her due and say symbiosis may even be a noticeable factor.

Sorry, differential reproduction, not selection.

If what you're saying is that Natural Selection isn't the only mechanism of evolution, then you are absolutely correct.

Artificial Selection

Genetic Drift
Genetic Hitch-Hiking
