Of course it brings up many other problems...
genetic integrity ....immune system issues...etc.

Of course ...if a crystalline species would avoid those issues...if such intelligence (which has been speculatively hypothesized in print) should ever exist ...

but my god....what a boring existence with only 1 sex ...in the species.
Yeah. But if we survive for another 1000-2000 years I guess we will be able build babies and when that way is suppior I guess we will go with that. The questions is if we build more/less sexes. At first I guess we will keep two but eventually we be able build the most effective way...which is...not really sure if we will build in computers or extra strong heart/brain and so forth.

Could be external things like the sun that triggers that, or war, sickness or economies. Who knows. The only thing iwe know it will happen, as long as we are alive. We will evolve.

Efficient or not, depends on whom you ask.

Of course no one really knows when sex was invented but chances are it was a very, very long time ago. Possibly even before, but certainly at least very shortly after multicellular organisms evolved.

One possible scenario, proposed by Richard Dawkins, was like this.

Every organism has a special group of cells whose purpose is reproduction. These can seed a new organism on their own or need to combine with a partner. There is nothing to say what the partner must look like. In the depths of time, the partners were probably identical. Even now we have certain fungi that reproduce by combining any two spores, there are no "male" and "female" spores.

Now, due to natural fluctuations, it may just happen that some of these cells are teensy-weensy larger than others. That has an advantage of bestowing the potential embryo with more nutrients, thus giving it a bit of advantage at the start of life. But a bigger size has a disadvantage too, in reduced mobility.

But what happens if some of the partner cells happen to be teensy-weensy smaller than others? They cannot give the embryo much nutrition but can be more mobile and more easily find the oversized partners.

So we end up with two opposing strategies: "both partners about the same" and "one big and one small but mobile". Over eons of evolution, the two strategies would diversify and the "big and small" would go to extremes, with the size difference in the order if 1000:1 or even more. And thus we arrive at what we today call an "egg" and a "sperm". We may of course have organisms that produce both cells, but it is more efficient to diversify that too, with some members of the species producing only eggs and others only sperm.

The cost of producing an egg is high, which means the egg is precious and the organisms producing them must treat them as such. The cost of producing a sperm is tiny, so the organisms producing them can afford to make them in copious quantities and waste them. The rest, including the anatomical and behavioral differences between "males" and "females" follows naturally.

If this is indeed how sex evolved, then it is very likely that a similar sequence of events unrolled elsewhere in the Universe. The aliens would indeed look very different from us, but the very basic law of natural selection would be the same everywhere and thus it is very likely that they would also come in two sexes.

Natural selection is only applied for young species. Later, energy is the decider.

What are you on about, Dave? Natural selection applies everywhere. Young, old, alive or dead. Why do you think we have a duopoly of just two mobile OSes? Natural selection!

Even if the dominant species on some distant planet were replaced with AI, the natural selection would not stop. Small fluctuations or even blind chance (like the one that did away with Mr T-Rex to clear the way for you) would result in some of them moving up while others dying away.

Energy? Ultimately, natural selection is driven by the struggle for resources. That's what it is all about: resources are limited, which means not all indoviduals can survive and reproduce. Most of them must die. Which ones die and which ones survive and produce the next generation, that is where natural selection steps in.

Resources can come in many forms. Materials, energy, even information.

I concur!!

I actually starting to doubt that we will actually see a full refund and that jolla stratergy from now on is focusing to sell license to tablet backer to force the money to stay in the ecosystem.

Hi. Has Jolla communicated this? I have not heard anything.

Sure Dave heard.
He is "attuned" to the Jolla frequency ...
His mind powers are focused...

Unfortunately it only works for Jolla...
And spare change on a tabletop .

Wait. Are we talking about telephones or telepathy. If telepathy, what OS is Dave999 using? Is it GNU/linux based?
