Let’s keep things simple two rules.

  • No giving sentience, This is a no brainer issue.
  • Let’s keep it to beings under the Animilia kingdom. “mutated virus/bacteria” is a common trope.

To start:

Let’s modify ants to have lungs.

Most insects are constrained by the amount of oxygen they can acquire through their exoskeleton.

Imagine how big they can get if they didn’t have that constraint?

    Cows now have tetrodotoxin like Fugu fish. Incorrectly prepared cows now have the chance to kill you.

    Both male and female mosquitos now drink blood and they spit some of the last person’s blood in you when they drink, causing them to spread blood borne diseases

    Mhh, insects in general IIRC are also constrained by the fact they have exoskeletons: i.e. their internal organs are just in a bag. So they can’t grow too much or they just squish I think.

    Imagine them being able to become vertebrates. You can have insects the size of cats I think before the osmosis breathing tubes they currently have are not a thing. Lungs would be the next thing I guess.

    Disclaimer: I’m not a biologist and just make stuff up from what I remember from high school biology, and it was last millennium!

      According to my sister-in-law’s then boyfriend (who was a biologist or an insect guy or something), spiders and insects can have lung-line organs called book lungs. So they have options. Creepy buggy insecty options.

        Oh right, I’ve read about that on coconut crabs I think. There you go, they are already half there.

    Give any animal the ability to photosynthesize. Now animals are of course complex creatures that need a variety of nutrients to function properly, and the number of chemicals we’ve seen be able to be photosynthesized is low, but imagine only needing to nude sunbathe for like a half hour to get enough sugars to fulfill your caloric intake, including the less efficient carb->protein/carb->fat conversion and pop a pill for some vitamins. Imagine if all animals had that as a baseline and just needed to hunt/forage for nutrients and vitamins to support auxillary functions.

    Overpopulation would be nearly impossible despite massive population booms, with the only real limitation being physical space and the social dynamics of any given species or interspecies interactions.

      The reason you don’t really see animals that can photosynthesize (other than microbes) is because you don’t actually get that much energy per unit of area. Think about how much area a cow has to graze vs the surface area of the cow itself. And much of the cow’s surface isn’t even facing the sun.

    Give human level intelligence to gorillas, this is worse then just human level chimpanzees in the fact gorilla’s are beefy and could rip the average human in to pieces. With human level intelligence they would be a force to me reckoned with
