Body parts functions and "mutation paths" ?

Spread the word, and vote for a new body part to see in Species 0.7.0 every fortnight!

Glad you like them. When I clicked that page I did a double take and was like, "I think some of these have developed on my islands". :)

These are about where I think the game in it's finished form should be starting at the earliest. I could see non-chordates of equivalent complexity but we are already dealing with distinct plants and animals. That's not a division that would necessarily even arise on another world starting from the cellular level.

Wait... no, I found it!
Those are cool, especially if they were the first aquatic creatures.

sooooo what was the point of that quote?

Showing off more of Vetulicolia?

Ah... found it: "Those are cool, especially if they were the first aquatic creatures."

Quote tags claim another victim. :)

Yeah, I love these things. They aren't the first aquatic creatures since it all began in the water. They are however probably as close as we can get to the ancestors of not only vertebrates and arthropods but starfish as well. Starfish are bilateral as larva and closer to us than sponges and jellyfish are. Maybe we'll have radials yet :)

They are basically the closest thing we know to the first animals we think of as animals. Things with mouths, guts, skin, muscles, internal fluids. Just enough to get you started without locking you in.
Early deuterostomes... that actually means we're more closely related to these guys than we are to scorpions and spiders.
The best part is their "very uncertain" affinity. If they are early deuterostomes they are ambiguous enough to pass for arthropod ancestors as well. The Vetulicola in particular have a carapace-like beak thing at their mouth. I doubt we can be sure whether it was keratin, chitin or cartilage.

So what I get out of that is that chitin isn't necessarily off the table for chordates and the early beaks we see in Species, in fact a lot of features I thought were rather advanced, actually match up to various Vetulicolia very well.

Huh it looks like they may have found something even closer to the base: http://www.sciencedirect.com/science/ar ... 6811001586

It's practically just the textbook diagram of what a creature with an anus looks like.

Also at about the width of a human hair it may be as close to bacteria as we need :)

I still love the Vetulicolia though.
