cambrian_exp Posted August 26, 2005 Share Posted August 26, 2005 well i found this alternate theory which modifies evolution and its called panspermia , well i havent read much abt it but just read it and tell , i think this theory is not explaining the mechanisms of evolution . http://www.panspermia.org/ Link to comment Share on other sites More sharing options...
swansont Posted August 26, 2005 Share Posted August 26, 2005 Panspermia replaces abiogenesis, while not modifying evolution at all. And it doesn't even do that - it just moves the issue somewhere else. Link to comment Share on other sites More sharing options...
cambrian_exp Posted August 26, 2005 Author Share Posted August 26, 2005 what is abiogenesis? Link to comment Share on other sites More sharing options...
Hellbender Posted August 26, 2005 Share Posted August 26, 2005 what is abiogenesis? The hypothesis that organic molecules were formed from inorganic ones. This is seperate from evolution that describes biological change. Evolution didn't start until well after the first self-replicating molecules were formed.

Phi for All Posted August 26, 2005 Share Posted August 26, 2005 From the link: The same kind of truce has helped, to a lesser degree, the Darwinian paradigm for evolution and the origin of life on Earth. The theory says life originates out of nonliving chemicals and evolves to higher levels of organization simply by following mechanistic laws.It's hard to take them seriously when they lump TOE with the origin of life on Earth. There could easily be some truth to organic molecules being seeded from cosmic materials, but what difference would that make to evolution?

Dak Posted August 26, 2005 Share Posted August 26, 2005 Or abiogenesis for that matter. As swansont hinted, if life on earth started from panspermia then life would still have had to have arisen wherever the pansperm(?) came from; meaning abiogenesis would still have had to have happened, albeit elsewhere. In the abscence of evidence spesifically suggesting panspermia occoured, okkrhams razor suggests terrestrial abiogenisis is the most likely model.

CPL.Luke Posted August 26, 2005 Share Posted August 26, 2005 does it really matter if abiogenesis occured on earth or not? I don't see much of a difference between having a couple of dna molecules form on earth or having them form on anouther planet and landing here.

Hellbender Posted August 29, 2005 Share Posted August 29, 2005 this is a little bit belated, but what exactly is "creationalism? Link to comment Share on other sites More sharing options...
