Broken Phalanges(blue on the middle image)AKA toes and fingers Broken fingers. humans can still use their hands with one or two broken fingers, (better with a splint) but a wolf is not running on broken fingers since all their weight sits on them. Broken toes. likewise since wolves are digitigrade and humans are plantigrade a human can walk (or limp) with ...

The species is parasitic in at least one stage of life. Glowing eggs attract creatures that want to eat the egg (since eggs have lots of fat in them, and don't run away or fight). (Thanks to an excellent comment by @HenryTaylor.) Thus, the "egg" isn't really an egg like we think of them, but actually bait for transfer to a host for the next stage of life. ...

Wikipedia says: All dogs (and all living Canidae) have a ligament connecting the spinous process of their first thoracic (or chest) vertebra to the back of the axis bone (second cervical or neck bone), which supports the weight of the head without active muscle exertion, thus saving energy. This ligament is analogous in function (but different in ...

On Earth poisonous animals are often brightly coloured, e.g. Poison dart frogs. Perhaps bioluminescence evolved as a signal that something is poisonous, and the eggs are poisonous to predators, or pretending to be.

Both Arms If I incapacitate both your arms, you can still walk and run. If you turn into a wolf then you are limited to pushing your torso across the floor. Still has a consequence for a biped but not nearly as severe as that for a wolf.

That’s a real thing. The pump console usually comprises several rotating motor-driven pumps that peristaltically "massage" tubing. This action gently propels the blood through the tubing. Or The pumps used in VADs can be divided into two main categories – pulsatile pumps, that mimic the natural pulsing action of the heart, and continuous flow pumps. ...

This a complicated answer because perception is created at multiple points in the optic chain starting with the lens (which is slightly colored and therefore actively filters out UV and purples) to the optic nerves (which are sensitive to three main peaks of the visible EM spectrum) and finally to the brain that perceives and translates the nerve impulses ...

I don't think it is viable. If you want to propel the athlete of mass m to certain velocity v starting from rest, you need to provide a momentum $P = m_a \cdot \delta v_a$. The same momentum has to be given to the expelled gases. The average bowels should be around 10 meters long, and let's assume they have an homogeneous radius of 1 cm, it means the ...

The neuro-pathways of the suits are very simple when they are "built". There is a large cluster around the neural-link port that handles all the sensory input from the suit to the human and all the control input from the human to the suit. Over time, this cluster specializes and becomes more complex to more efficiently handle this transmission. Eventually ...

The answer is "it's possible, but VERY unlikely". There's a lot that goes into this, but the short answer is that there's no guarantee the proteins that developed on this planet will be compatible with our biochemistry due to a little bitch of a thing called chirality. And even if you get lucky and find a planet with compatible proteins (possible but ...

The simplest way for an organism to start a fire is with a pyrophoric chemical. This is a chemical that will ignite spontaneously when exposed to the oxygen in air. All your fire-starter would need to do is produce the chemical in a special anaerobic organ that would keep it away from oxygen. Then the organism could spray the pyrophoric liquid as a ...

Speaking from a software guy's perspective. If we (homo sapiens) had evolved without the pinky finger, some tasks would be more difficult, and some would become easier. Any task that has to do with gripping would become slightly more difficult, as the pinky allows your hand to more fully encompass an object (5 areas of contact for gripping a baseball as an ...

Let's assume bio-luminescence is rare and not the norm: if the environment is full of bioluminescent rocks, then it would be more a camouflage. So back to basics: bio-luminescence makes things visible, and usually more recognizable and identifiable. How could this provide any advantage to an egg ? Identification for better protection. If from a social ...

Solenoglyphy is not the only envenomation mechanism that snakes can use there are also opisthoglyphous and proteroglyphous snakes, I would suggest that either of these mechanisms would be more suitable for a fox that has to tear and crew its meat. In particular opisthoglyphous teeth are almost unaltered in their morphology except for surface groves that ...

Considering that all those lower-gravity environments have artificial life support, which (presumably) is kept at a nice, even temperature, then if we presuppose that the temperature is slightly warmer than what a human on earth in the natural environment experience (in other words, nobody ever freezes or feels chilly), then perhaps some observed phenomena ...

They just need for the liquid to have a very high surface tension or even be slightly gelatinous (like napalm, which was developed for the same needs you have). Then they can employ a relatively simple two-chamber mechanism, with a larger reservoir chamber where the liquid accumulates, and a smaller chamber with muscle walls and a sphincter to shoot the ...

Most plant food on Earth won't sustain people. That's why people were hunters before farmers. Meat, at least earth-meat, is easy to digest in almost every form. Few plants have anything edible about them, as a defence mechanism. Consider the Apple Tree, it only produces apples specifically so that animals/birds eat them, walk somewhere else, and poop out the ...

One option is to have suits simply "enjoy" having human inside. Neural link would feed thought, dreams, ideas and emotions to the suit that the suit is not able to create, but is able to receive them through the link and appreciate, even enjoy (or to go to extreme, become addicted to) them. Another, similar, idea is to have suits consciousness limited when ...

Maybe yes, but not through that mechanism. You don't necessarily need heat and pressure to make diamonds, and those are not usually things that we biological squidgey things use to grow things like horns, nails and scales. I think there are two ways currently used for creating artificial diamonds on an industrial scale, one being the one you mention (High-...

I think this may be a combination of some natural effects of low gravity and an opposite of the "Heavy Worlder" trope. For the first; astronauts actually do "grow" when spending time in Zero G. True, this is just a matter of the spine expanding a bit (just 2" or so total) in the absence of gravity, but it would be easy to extrapolate "low gravity" to "...

There are a number of issues here. Resolution Ok, so let's say you create a new kind of cone that's sensitive to UV. Where are you going to put it? The retina is already jam-packed with cones, so you need to remove other cones to fit the new cones. So your guys can see UV, but their sensitivity to one or more other color channels gets worse. Now, if these ...

The usual logic for such tall low-gravity creatures is that we tend to assume taller is better, and low gravity removes some very real shackles which make tallness unstable. I think one of the most fundamental advantages of such tall creatures is the ability to put sensor apparatus such as eyes and ears and noses far from the center of gravity of the ...

Telomere-therapy The telomere is basically a protective layer for genes that prevents them from being truncated during cell division. After some time the telomeres are truncated so much that the genes will get truncated next - which means that the body dies. Theoretically by lengthening the telomeres you could achieve immortality - or at least very, very ...

Trunks are unbelievably adaptable, but they require a large amount of time to learn how to use. Elephants could easily do what is needed. Trunks are as dexterous as a human hand, and in many ways even more dexterous. The price you pay for a trunk is complexity. The human body has about 800 muscles to do everything, from manipulation of objects with our ...

Perhaps the egg laying creature is the apex predator in its world, with such a overwhelming predatory advantage over all other life, that even its' newborn offspring can defeat anything which might be attracted by the light. The glowing eggs might serve to provide its occupant with a first meal.


14

Teeth It depends on the reason. If the human wants to stop the wolf-form from doing harm then they should have all their teeth removed and have false ones made. The false teeth won't fit the wolf. They could also have implants and unscrew them at night. A werewolf that can only suck wouldn't be too frightening.

You want napalm. The substance which gives it its name - it's made of aluminum naphthenate and aluminium palmitate - serves as a thickening agent. This allows it to stick to surfaces, part of what made it so successful, but also means that it maintains a fairly cohesive spray. As you can see in the picture, napalm can do all the things you specify. It can ...

Short answer: A centaur can't reach his own hooves, but can reach the hooves of others by lying down or kneeling. One centaur can maintain the hooves of another. Better answer: There are a few reasons why horses wear shoes: to keep their hooves from cracking on paved roads; to gain better grip on cobblestones, in slippery conditions, or during races; and ...

To expand on JDlugosz's answer about perception of the colour wheel - with the VERY important assumption that these modified humans are born with enhanced eyesight - I think your modified humans will lose the ability to perceive the colour pink. The colour pink is what your mind calls the joining of both ends of the visible spectrum. That's why pink is ...
