About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

That technically is the definition of sentience, basically consciousness with the ability to react and have awareness of your surroundings. I think the word your looking for is sapience, which is the ability to contemplate and act productively using knowledge and reasoning

[–] HauntedCupcake@lemmy.world 24 points 6 months ago (2 children)

I think jumping spiders fit into the sapience category then. They're known to learn different prey types and change their hunting strategies accordingly, even learning typical behaviour and being able to pick out sick/injured insects and figuring out they don't need to go full stealth.

They've even been observed to enter REM like dreaming states, where it's assumed they process a lot of the visual information they picked up throughout the day.

So basically every animal higher than the jumping spider might fit into the sapience category, which is kinda wild to think about

Jumping spiders also seem to be genuinely curious about things. Anytime I want to take a photo of one, it stops, looks at the camera, jumps on it to check it out, and then leaves. Kinda like I'd take a look at a new product on display on a supermarket shelf

Oh great, even more reason for me to be terrified of spiders

[–] HauntedCupcake@lemmy.world 10 points 6 months ago

Jumping spiders are little dears, all of them are harmless to people and don't spin webs. Very polite guys

Naw you're fine. If you give it a chance you can even learn to find them cute.

Look at it, it's cuts as hell. (I'll hide it behind a spoiler tag. A phobia is a phobia, after all)

Well that's the word we should use when discussing animal intelligence then.

[–] agamemnonymous@sh.itjust.works 1 points 6 months ago

It is. We say sapience when discussing intelligence, and sentience when discussing consciousness.
