I wanted to try something new, so here's a minigame

A pixel evogame started on the evogames subreddit. Its main conceit was to evolve a single organism linearity, never branching. Despite this, there ended up being a branch by accident simply because of users posting within close proximity to each other, time-wise. Only one of the branches was declared "canon". Despite this, the branch will be portrayed in the evoweb.

Starting Post
In this minigame, instead of evolving a whole ecosystem, it will focus simply on a single lineage of organisms. This means that instead of a branched evolutionary tree, there is one organism that is evolved linearly. The rules are simple:

Make a slight change to the organism and explain the reason for the adaptation. In this game there is no branching of the species, so simply reply to the latest comment. You can not evolve the organism twice in a row; you must wait until someone else changes it. Remember you do not "own" the organism and don't get salty if someone changes it in a way you don't like. Lastly, since there is only one lineage, make relatively small evolutionary steps (don't go from a tiny mouth to huge mandibles in one step.)

Obviously for adaptations there must be something driving them, so let's say assume that this ecosystem is on land and has various mosses and small plants, as well as small worms and insect-like creatures that live on the ground. '''DO NOT ADAPT THESE ORGANISMS! ''' The organism you will be evolving is the Primu (I wanted to try something new, so here's a minigame), a land-dwelling sluglike creature that currently eats moss and plant leaves. It has primitive eyes and no skeleton, and is preyed upon by the insect-like creatures.

Have fun and be friendly!

Primu's lineage (I wanted to try something new, so here's a minigame)

I'll start it off. Primu develops small stubs of flesh that help it maneuver faster.

Primu

changes in color to camouflage with the leaves and moss.

[–]OptumMum 2 points 6 years ago

Primu

Grows a clear exoskeleton that protects it from attacks. Clear to allow the camouflage capabilities to still work.

I cleaned up the image a bit, try to keep the black border.

Primu's front appendages grow a bit more to help pull it along the ground.

[–]Lite-Black 2 points 6 years ago

Primu grows eye-stalks to better detect predators. It's exoskeleton also slightly rounds off to better defend it's rear. It's back stubs get a bit stronger to haul the slight gain in weight.

[–]OptumMum 3 points 6 years ago

Primu gains an adhesive goo that helps it climb trees and glide faster thanks to its strong front limbs. It also grew small claws for better grip when being attacked while on trees.

There are two responses to the last one, but there can only be one lineage. Did you or WackyWocky post first?

EDIT: Post in response to this one

/u/optummum was about a minute ahead...almost exactly

[–]cromlyngames 1 point 6 years ago

Primu that leave attractive chemical signals (similar to those given off by fresh moss) in its slime trail are found by other Primu more often, and outbreed the competition. There is no outward change, yet.

[–]Azolio 1 point 6 years ago

Primu develops a primitive horn-like growth to deter predators, as well as slightly longer and more sophisticated eye-stalks for improved vision.

[–]WackyWocky 0 points 6 years ago

Because Primu is not specifically fast, does not have large mandibles or any sharp claws, it has issues catching and holding on to prey. So it develops poison sacks within its body that give it a mildly paralyzing bite. This makes large prey slow enough to bite more, and small prey entirely paralyzed and easy to eat.

Primu changes it's exoskeleton to a moss texture fur in order to fit in to it's mossy environment. Its head remains with a transparent exoskeleton in order for it to have the same power to its paralyzing bite. [img]http://i.imgur.com/RZMhmfF.png[/img]
