They've been studying this thing for decades, so I'm assuming that they've been fairly thorough and careful not to make any assertions that aren't backed up by reams of evidence.
As far as I can tell, the only place where this claim that it is "man's oldest relative" is in newspapers, and not a single one of them cites where the fact came from. The original study doesn't mention anything about this idea in the abstract, so it's probably safe to assume that it is another alternative that I hadn't considered --- journalist sensationalism. It's obviously a new form of life, and there are claims that it's ancestral to the eukaryote (like a human cell), but since this organism is still alive and has been evolving for a billion years, it's more likely just a cousin of a sort, sharing a common ancestor --- it would simply resemble the common ancestor more than we do.

My girlfriend is mad at me. Perhaps I shouldn't have tried cooking a stick in her non-stick pan.

You could be right, or you could be making several assumptions that are not based on fact.

It's likely that the only way for you, I, or anyone else to truly grasp the full implications of and lineage of this peculiar little critter is to dive head-first into all of the literature as well as speak with the scientists that have studied it for the past two decades. It probably wouldn't hurt to also get out into the field and get some hands-on experience.

Either way, it's an interesting discovery and one worth sharing.

But if the Collodictyon is an ancestor of humans, then why don't we see Collodictyons giving birth to humans today?

It was just a fucking apple man, we're sorry okay? Please stop the madness Laugh out load

I am forced to concede, evolution is a myth. Weeping

Man, I don't read nuttin without considering sensationalism. Tongue

Here's another article. This thing is a eukaryote, and we're a eukaryote, so obviously... sensationalism. Tongue
