    But what if the human form is a prerequisite for evolving into the space age? We wouldn’t need so many tools if we were strong as a crab to begin with

    Neal Asher’s Praedor Moon is a fun read if you want to see what advanced humans would do against space faring crabs.

      The entire Polity series is great, but my favourite parts are always when we follow a Prador perspective.

    Project Hail Mary got this really right. The aliens are big rock crabs

    You guys should read the Stormlight archives. Fuckin everything is a crab, even the plants.

    Life can have infinite forms and can exist and evolve in the most inhospit environments. But an advanced tecnologig species only can exist in certain environments and with reduced posibility in their appearence. Aquatic beeings can be intelligent, but never can create advanced tecnologies. The basic condicion of advanced tecnology is the domination of fire and electricity, not possible in the water, it need Oxign in the atmosphere.

    They must have limbs skilled enough to handle and construct this technology, a complex communication system, and a binocular vision system (for this reason the most used in all species) to perceive their environment. The humanoid shape is one that best fits these maxims and therefore it is quite possible that an advanced species would also have a more or less similar shape.

    It is known as convergent evolution, when unrelated species have a very similar physique to each other by living with the same challenges in similar environments. Evolution always use similar solutions for similar tasks. A good example is the genet, which looks and behaves very similar to cats, even with retractil claws), but they are a completely different species (Viverridae)

      Tech needs electricity and fire is not universal. That is what we use.

      Our brain is lot more complicated and efficient than the computers we make and it uses ions, in liquid media. So something that lives in water could definitely be able to make something that would be able to use similar things to do processing. Water is also really good with doing things, it’s flexible but doesn’t compress/expand like air does. Think about hydraulic systems. You can make them smaller and smaller as your tech progresses. Mechanical things using metals and such would work in water as well. Think about gold and such that can be used for electricity as well, we don’t use it because it’s valuable, but an alien world could have abundance of gold for them to use.

        Don’t care how smart you are, you ain’t shit without metallurgy followed by electricity. No metallurgy, no electricity, no tech.

        Ever read a science fiction novel where the aliens evolved underwater? The author has to twist the story in knots to try and explain how they gained anything advanced without fire.

          It can be cristals and photons. Carbon is the basis of life because it’s good for looooong molecules. But it’s not like it’s the only option. It may not even be the best option on planets with different temperatures or pressures.

          Anyway life may not even need food or care about the passage of time.

            How do you build actuators that react to light without electricity?

The humanoid shape is one that best fits these maxims and therefore it is quite possible that an advanced species would also have a more or less similar shape.

      Elephants meet all of these criteria as well. A complex limb (their trunk), a complex communication, and binocular vision (although I don’t see why this is necessary).

        Complex limb? Let me see an elephant tie a granny knot. Maybe with training? OK. Do a square knot.

        Complex communication? Elephants have communication skills on par with a 3-4 year old human. An intensely trained dog might top 200 words. My vocabulary is an easy 50,000 words. Yours is too.

        Binocular vision is a must, that’s a given. Damn near every animal on the planet has it, even some worms.

    If this post is awakening some weird feelings in you, there’s an episode of Futurama you might want to watch.
