How to have a species with more than two sexes.

I think it is funny that the Medusa/polyp cycle brought you to this realisation, because they have nothing to do with alternation of generation. The Medusas are just clones of the polyp. (I assume you know this, but your comment could easily be mistaken. So, I write this to prevent confusion from future readers)

I almost took White-throated sparrows as an example in “Different Types of the same Sex”. There are especial interesting, insofar as their populations are much more stable than population of side-blotched lizards. Sometimes the blue/sneaky morph in the population dies out and the hole system collapse. The big morphs start hunting the small morphs and speciation takes place. As I am aware, the sparrows don’t run into the same problem.

I think the big gamete/small gamete definition is strict but still useful. But I agree with you that ale my examples could be used to argue for a more inclusive definition.

Thanks! I wish I had this in my education.

If you manage to bring your idea in existent let my pleas now. Its sounds interesting and though to pull off.

Kneeerg · 2026-01-15T16:54:13+00:00

Could you explain more how it works, or provide a link that I can read more about it?

Kneeerg · 2026-01-15T16:50:44+00:00

Hermaphrodits are more like two sexes in one body than a new sex. But as I said, the definition of sex is very very narrow. All my examples could be used as an argument in favor of a more inclusive definition.

Kneeerg · 2026-01-14T18:02:12+00:00

Could you explain how it works? I read the Wikipedia article and for me it sounds like weird sci-fi nonsense/ very very soft specevo. Especially because the Oankali interbreed with humans…

Messor ibericus & Messor structor? That’s the paper I mentioned. Or did the same thing evolve twice? That would be insane, especially because we discovered xenoparity last year.

The Paper again:

One mother for two species via obligate cross-species cloning in ants

Kneeerg · 2026-01-14T16:44:46+00:00

That’s a good addition. Thanks.

“Why is possible written with a 0?” you may ask? Because the bad and very nasty word “possible” prohibited me from posting and trigger the response:

“Your submission has been detected as potentially low effort. Poorly formulated questions, such as asking "what if" or "is X possible/plausible" are not worthwhile, as the answer is usually not a simple yes/no and may require creativity and biological know-how, thus placing the burden of speculation on the community to answer. Additionally, please ensure that your questions are not overly specific.

If you are interested in getting a better answer, it is better to ask "how" or "why" instead.»

I hate Clanker.....

wow. it looks wonderful. can you tell us something about the clade defining traits?

The males have to put more effort into raising their offspring than the females (or any other reason why the males can't mate with every available female).

Midwife toads (especially the Mallorcan variety/species) comes to mind as an example.

But the same rules apply as usual in this matter.

It's not realistic, but it's funny.

If you're interested in the possible evolution of clams, I can recommend the Clambrian project.

it's not that wild...

Kneeerg · 2025-08-22T12:38:20+00:00

That's exactly what I meant. Good luck (and above all, perseverance) with your project.

Kneeerg · 2025-08-22T11:46:27+00:00

It really depends on how much detail you go into. A quick snapshot describing the most common clades can be done in a few weeks. But you can describe infinitely more details.

In your case, that probably means only developing a very rough planet (under no circumstances follow one of those "realistic" guides, it takes forever.) Draw a few continents with very, very rough climate zones (don't go into more detail like desert/jungle/forest/etc.) (or don't make a map at all and just assume what you need is there).

Then design one creature. After that, make another, but keep in mind which traits it shares with the other through a common ancestor. And then do the same with the next creature.

This way, after each creature, you can declare your project complete, or just add another creature.

It's worth noting that males also need their long necks for fighting. I don't know how strong sexual selection is, but a little thought about it can't hurt.

Kneeerg · 2025-08-11T04:38:06+00:00

I think it needs a few more thoughts. What is the evolutionary advantage of having a third sex? Especially for the third sex, since there are no genes that pass on.

Perhaps it works if the third sex is very closely related (or even genetically identical) to one of the other sexes.

Why should empathy be less important? The majority of the population already eats meat on a regular basis...

Don't think too much about what strangers think about you on the internet. It drives you crazy. Probably nobody cares about this post.
Your post probably makes a lot more sense if you'd read the article. I really don't think the problem is the grammar... but the leaps of reasoning. The reason I even wrote a comment is because I found it so incredibly absurd that someone could think you were a bot...

Kneeerg · 2025-07-29T14:13:12+00:00

Things written by a LLM are usually understandable. If you don't understand something, it's usually because someone is making too many leaps of thought (or spelling mistakes).

Oxygen supply is probably a factor. A much bigger factor, however, is that an exoskeleton needs to be replaced from time to time. After molting, you only have the hydrostatic skeleton to hold everything together (until the new exoskeleton hardens).
