Uncanny Valley The uncanny valley is an interesting phenomena discovered by Masahiro Mori, a professor who made realistic robots. Generally, the more something looks like a human face, the more people identify it as resembling a human face, but at a certain point (between 75% and 90%) people stop identifying it as a human face. The reason for this is a ...

Developing comments between @AlexP and me into an answer... As other answers have said, candling of reptilian eggs is possible. For in ovo testing of chicken sex, if the male and female have different pigmentation or other easily-distinguishable features then this can be highly reliable. There is no reason to think this would be different for reptiles. ...

It doesn't blink. Unless it knows it is being observed, because a very little kid once asked it why it did not blink. It had not noticed blinking before then. Now it tries to remember to blink if it thinks it is being observed but it is easy to forget if it is concentrating on something else. Its face does not move unless the shifter moves it on purpose. ...

Let's start with a dose of reality I have "superior night vision" (hah), aka, super-light-sensitive eyes. As a teen I could read comfortably under a full moon and I can see comfortably at light levels that cause most people to trip over tree roots. My highlight was as a kid when rangers turned off the lights in some cave tour in Montana. I've been ...

You would end up with a head full of horns or quills. Human hair is made from keratin. It's the same with your fingernails and toenails. In fine form, hair is soft and flexible. With thicker amounts of keratin, it becomes stiff. In the animal world, most horns have a bone core covered with a thin sheath of keratin. Since we lack boney protrusions on our ...

In this setup lying will not change the color. My only point is that it will be harder to lie and I want to know the loopholes so that I can get my story straight Well, I can think of a fairly big loophole. Their eyes may show their emotions, but there's nothing stopping them from lying about why they're feeling that particular emotion. It's a specific ...

It’s too perfect. A major breakthrough for animation was the addition of imperfections. Before high resolution texture packs allowed for the addition of skin flaws (and before people realised the flaws were essential) animated characters simply looked fake. Humans simply aren’t perfect, no matter how hard we try there is always asymmetry, blemishes, spots ...

Masters of the Jungle Your halflings are well adapted to life in the jungle. Their small frame makes it easy to maneuver through dense foliage and their low weight makes it easy to support themselves on branches. They are not as weak as a human child. In fact they are surprisingly strong for their size. Smaller creatures often have more strength than larger ...

The mindless clones are used as "friends with benefits" by their owners, and for those kind of benefits no android or robot can compete with the real thing. Of course this is not something publicly spoken of, but is mutually understood that the clones satisfy all the needs of their owners. That is accepted as lesser evil than having real humans ...

Giant pupils. Humans are limited in how big our pupils can get because somewhere along the line, evolution selected individuals where the iris was small enough that you could see the whites of our eyes. Probably that gives some sort of cultural benefit as one can see where a person is looking, and maybe you will later feel fondness towards a baby you saw ...

You can go for something similar to the plates on armadillo tails It will protect the tail and allow some mobility. You can also add blades to the plates, so that it can be used to hurt enemies approaching from behind. Just be sure she doesn't wiggle it while in a friendly crowd, for obvious reasons...

Well OF COURSE you want your Spare Parts storage clones to be mindless. We all want to live forever, or a good imitation thereof. So it is a very good idea to have a spare body hanging around, one that is 100.0000% genetically and structurally compatible with your own. But.. The ethics and morality of killing another person just to replace that arm you ...

First and foremost, disease would be the best weapon to employ against an enemy that outclasses you in all physical respects. Giants like to fight and are great at breeding? Good, they'll be in physical contact with each other more than enough for one good bug to tear through them. There are plenty of examples in history of why this is so effective and ...

Yes Simple answer is yes. People have an image of themselves. This image changes over time and the idea of being human fits into this. But there are plenty of irregular personal views that go along with it. Some are harmless, some are just strange and some turn the world upside down. There is a person who is convinced she's a cat and tries to become one as ...

If it did evolve it would probably form as a development of the parietal eye. This is a third light sensing organ that exists in some species of fish, reptiles, and amphibians. This organ is missing from all extant birds and mammals. For such an organ to evolve into a second pair of eyes there would need to be a very strong selective pressure that would ...

Farmer traits: Fecundity. If you are a farmer you are more likely to have food than if you are a hunter/gatherer. If you have food it is less likely the kids will starve. If you have lots of kids who are not starving you have more people to help with the farm work. Patience and focus. There is a theory that attention deficit disorder is an old ...

For various values of "dryad" this is entirely possible. Look into agrobacterium tumefaciens for inspiration. Those bacteria alter the DNA of their host plant to create a tumorous growth. Look into gall wasps for an example of induced growth that has to do with growth vectors/plant hormones and possibly RNA/DNA viruses - this growth is much more structured ...

You need to constantly threaten those humanoids from the back - for example big silent owls and manual tasks that require a lot of time The eyes need to provide an advantage for these humanoids, so there needs to be something they excel at because of their eyes at the back. The first thing that comes to mind are very silent predators. If your humanoids are ...

Don't make them so weak Make them proportionately strong, which makes them weaker overall but doesn't critically disadvantage them. They're going to have to be appropriately strong just to survive, the strength of a 5yo is not enough. Small size isn't such a disadvantage They're more agile, without so much bulk to move around they can change direction much ...

This is quite a difficult question to answer, for the sake of the bigger picture. You see, the arms require skeletal support (primarily the clavicle and scapula). As well as muscular support (all the muscles in the arm and the pectorals on the chest). So, what you would need, is a skeleton with seemingly redundant bones to support the limbs spread out to ...

Spread out flat a.k.a. (apropriately enough) spreadeagle. To decrease terminal velocity, you want to maximise drag, while minimising mass. So, lightweight/honeycombed bones, and flaps of skin like a flying squirrel SCIENCE! The formula for Terminal Velocity is $V=\sqrt{2mg/(ρAC)}$ - that is to say, the square-root of twice the Force due to gravity ...

Invalid wobbles When I watched Downsizing, something felt really wrong in the scenes where downsized and regular people were interacting, but it was so hard to put my finger on it. I think it was because subconsciously I expected the fluid mechanics of air, gravity, and so on, to have created differences in motion between large and small people. Different ...

People don't really trust the androids The uncanny valley is a thing, and this reason only would put the android at a disadvantage against a clone: the idea that 60% of people who would choose a human being against a realistic android, even if more expensive, sounds like a very plausible scenario to me. Moreover, many people think that the android mind is a ...

In addition to the other answers: Make your humanoids small! The advantages of small size for falling are a universal principle of elementary physics, clearly and memorably explained by J.B.S. Haldane in On being the right size: You can drop a mouse down a thousand-yard mine shaft; and, on arriving at the bottom, it gets a slight shock and walks away, ...

This is pretty much a let me google that for you kind of Q&A: Reptile eggs can be candled, just like bird eggs. (Probably because, you know, birds are dinosaurs, etc.) Reptile keepers can certainly determine if an egg is viable or not. As with humans and ultrasounds, your sophont reptiles could paint or photograph the resulting images as Junior ...

I have moved my entire household including cages with birds between cities. The birds do NOT stay on their perches. The motion of the vehicles is so unnatural and extreme that they hunker down on the bottom of their cages and weather the storm. Granted, intelligence would help considerably. Obviously the wind whips branches around, but have you ever ...

It’s an illusion and only appears to hover. 1) They wear their hair that way. 2) Rite of passage into adult hood and everyone wears one after, it is a simple metallic ring and is attached to the back of their head. 3) Genetic drift has allowed for horns to grow. Their horns generally sprout from the back of the head and tend towards symmetrical design ...

You can hide your eyes In such a culture it might be normal to hide your eyes so that you would normally not show your intentions to others. If this is the norm than the eyes are no problem in normal everyday conversations. It would be difficult if you knew someone really well and wouldn't hide your eyes normally. That would be extremely suspicious and it ...

I see some serious disadvantages: Such hairs would fold and crease versus bending, leading to hair snapping off and/or major split ends much more readily. Such hairs would, of structural necessity, have much thicker walls, leading to a massive per-hair weight; as a result, hair follicle depth would need to be far larger, leading to a monstrously deep ...

So you gave two pieces of information that are very helpful: Roman Era tech and distances of 350-500 miles. Given that they are in an archipelago-style region, I would recommend ships similar to the Polynesian islanders who settled across the Pacific. These ships are open, leaving you without any problems from height. Really, the more pressing concern is ...
