Hello! another idea! want to hear it? no? OK ill tell it to you anyway!

If you built a creature like a lizard that could detach its own tail! and it writhes around on the floor and distracts the predator! after a while the tail regenerates.

leave me a reply if you like it!

I think it's a nice idea. Sea-Stars, octupuses and other organisms do have regeneration, cells too. I don't think it is too complicated to add early.

Ps: I think this topic is on the wrong place.

Probably.
I dont' know how we could code it, but regeneration is a definite advantage, evolutionarily speaking.

That is why lizards eat a lot, right?

So. hum... regeneration should take a certain amount of energy.
So it would disturb evolution process or it would give the creature or cell hunger?
How would that be added? I don't think it is considered a organ matter but a cell characteristic. Each cell or certain cells of the supposed reptile can regenarete.

I have no idea.. I'm not a Giant-brained person. especially when it comes to Really big science that I haven't learned in school yet. But! energy comes from other places, not just food. in the plant's case, most energy comes from sunlight. (i think)

Energy comes from sugar (don't know the translation again) so yes... now that I think of it it would make sense for the creature have more hunger...

Plants produce their food, thus their energy.
I actualy made that question because I don't remember where I saw in the forum that evolution would require energy.

Since an amputation affects the individual, regrowth makes them require more food.

This may belong in organ design or somewhere else but I'll post here just for the Belgium of it. Regeneration is the ability of an organism to replace lost or damaged parts. Regeneration in creatures with specialized cells and tissues goes in a few steps: immediately after the wound the cells left form something of a wall, swelling to prevent escape or entry. They then "dedifferentiate" forming an equivelant of stem cells which then divide and grow until they take up the space where the tissue used to exist and then redifferentiate back into the (more or less) specialized organs. Not all creatures can regenerate this way and it's highly energy expensive to do all that. Newts are a model organism for regeneration, they can grow back even their tiny little hearts and spinal cords. Most organisms just don't have this though. For most, an injury that severe is too much and they die immediately (hard to evolve to survive decapitation, being torn in half, etc) like many flatworms which have X number of cells which never divide, despite being mega simple. The opposite is true in complex organisms where it's just infeasible to carry the genetic information for every type of cell, in every cell. Hence the use of generic scar tissue for filling up wounds in humans. Point is, regeneration is expensive in terms of evolution and use but could pry just be handled in the OE as a property of all cells in the organism, or as specialized organs rebuilding the others. Both could be used.
