Historically, male strength has served us well in any type of construction job, or things like combat. However, as industry and tools develop, this becomes increasingly less significant and necessary. Especially the invention of industrial tools to make manual tasks easier, contributes to the difference being less significant. While historically a man with ...

No At least, not significantly greater. The theory that the pain of childbirth is what stops humans from having children isn't that substantiated - while childbirth is painful, it's not why people don't want to have children. I suppose on a subconscious level, it might affect a small percentage, which is why I say that it wouldn't make humans significantly ...

While possible, I don't think that a society of transhumanists would do what you're proposing as it would be a massive waste of resources. Saturating the entire atmosphere with enough "nutrients" to make it practical for transhumans to use would be a colossal effort and probably completely destroy all native ecosystems. Most air never gets inhaled by humans ...

This would be the age range in which humans could have the highest base fitness. It is commonly believed people still develop their bodies until the age of 25. Afterwards, the body stops developing and slowly deteriorates. However the largest parts of deterioration aren't too significant until the age of 50, after which people become slower and less ...

No there isn't. While on average, men are stronger than women, some individual women are much stronger than the average male, and vice versa. For all i know the maximum strength a human can reach is slightly higher in men, but that is just for extreme cases. The biggest part of the difference in average strengths is (somewhat dated) role models, and ...

Possible - it's a pinniped It's not horse-based, that's for sure. For one, horses are vegetarians, so shifting them to a meat-based diet not really so easy. So, if we're looking for a quadruped (or, at least quadruped-like) animal that can live in water, we're looking at a pinniped variant. Pinniped is a family of mammals which primarily include the various ...

One man? Definitely not. A few? More likely, but still improbable. The largest issue you would face is the nozzle spray size of the flamethrower. Vietnam era napalm flamethrowers were largely designed to get as much range as possible, making it effectively similar to a flaming squirt gun. While this is useful against less mobile humans, not so much for ...

In Latin America we have capybaras )we call them chigûiros in Colombia), it's not that common in cities to eat rodents since natives are the ones who eat them, but it seems capybaras have low fat and cholesterol compared to other animals: Is in Spanish, try using translator Also, capybaras have a fast gestation period: 150 days for 2-8 pups and each ...

I suggest looking into South African ostrich farms. While they haven't replaced chicken, they are a widely used food source there. Ostrich meat was widely available in supermarkets last time I visited, on par with "common" meats like pork, beef, and chicken. If you say that megapodes are easily kept as livestock, give lots of eggs and meat, there would be ...

This age range has the best blood. Children and the elderly are plagued with disease. Since ancient times, these vulnerable populations have been avoided by brujas because sickness reduces life force and threatens to break the spell. Granted, these populations today may not be dying of the plague, but tradition is tradition, and the old spells work best. ...

It is the Goldilocks Zone for life theft because of multiple contributing factors. Each one is not the singular defining factor, but have their own ideal age ranges of effectiveness. But by putting all the factors together, it winds up that the age range of 25 to 49 ends up to being the best likely return on sacrificial investment. I could see an urban ...

Ok, before I answer the main point, I'm going go into a little diversion which has really important implications: What's the gravity on your all-female world? Because the physical strength of the people on your planet (male and female) will be highly dependent on the gravity they live in. If your planet has a lower than Earth gravity (like say the 0.89g ...

Our liver and kidneys make already a pretty good job at allowing us drinking non pure water. Coffee, tea, sodas, liquors, are basically water based solutions with "pollutants" in them: caffeine, alcohol and other substances. They are all processed by our liver and kidneys and expelled from our body. The twist is simply to improve kidneys and liver to be ...

I would use the camel as template. The guy stores fat on its emblematic upper back "breast" and when the body needs water, it breaks down the fat to produce water. Say you approach these species as adapted to produce a reserve, increasing the fat/oil reservoir size.The act of lactating could be done away from away from food on weeks long trips. In our ...

It's a hippo. A big black horse-like creature that resides in pools, extremely territorial? Sounds to me like the very rare Celtic hippo. It runs underwater and lives in lake. It would explain the kelpie's kill count too - hippos are extremely dangerous creatures when disturbed. It doesn't eat them but it most certainly drowns anyone who comes near. Mind, ...

As soon as you have things like levers, wedges and wheels -- not to mention draft animals -- muscle power becomes a 'nice to have' rather than essential. Yes, big, hefty construction workers (of either sex) may get the job done quicker than small, delicate ones (of either sex) if they have to move a lot of bags of cement etc; and (crucially) your wages bill ...

Yes he could, cockroaches aren't immune to fire. Surviving the nuclear apocalypse has to do with not dying from radiation exposure. The actual blast and heat kill them no issue. They are also incredibly adaptive with regards to poison, which is what is typically used since it doesn't damage buildings. How intelligent a hyperintelligent cockroach hivemind ...

Simply said eggs. If we look at how many eggs most animals are able to put out it will dwarf the amount of live births(highest mammals do it around 30, while fish and insects can go in to the millions). And if you got full genetic control you could have the breeding mother be able to get pregnant straight after the first batch of eggs. After that it's a ...

I can’t think of any single task in the past or present which requires high strength but can’t be broken down into smaller parts or tasks. Sure, the average man might be able to lift a heavier log of wood than the average woman, but at some point you’ll always need two pairs of hands. We’ve always excelled at breaking things into manageable parts. I also ...

This already happens, with Padrón peppers. They are usually very mild, but you will occasionally get a hot one, so they’re sometimes known as Russian roulette peppers.

To drink seawater you can: Give them salt glands like various seabirds and marine reptiles have got. We already produce salty tears, so the human tear duct could be adapted for this. The downside is your people will look as if they are crying (or have an eye infection oozing salty liquid) even when they are not. Make their kidneys more efficient at ...

Pain "Natural pain" during sex is really not that natural for most people. Sure, some people have medical conditions which can make sex painful, but on the whole it's not painful, and enjoyable, so we can dismiss this point, as it isn't significant over the population. Pain during childbirth is not something most look forward to, but the vast majority of ...

That sounds pretty close to peak fertile age. Which is when the victim's native magic (all life forms have native magic) is tuned to the creation of new life rather than the protection of its own. This means it takes a much smaller magical shock to make the magic support another existing life (the bruja's).

Lymphocytes! Prime age humans have fully developed and functional immune system, children have not fully developed immune system yet, and senior age humans have immune system slowly fading. And because of dark arts and quite unhealthy rituals/ingredients they consume, bruja's immune system is usually quite compromised. Also its worth notice, that blood is ...

I’m going to assume that the blood in the lakes and rivers is only red blood cells. White blood cells wouldn’t survive in the open as there would be unlimited bacteria/viruses to fight against. Blood will naturally latch onto oxygen that’s in the air and carry the oxygen with it. That’s what blood does. Note that blood deeply submerged in a lake would not ...

Plesiosaur. It's no stretch to say these guys laid their eggs on the beach like turtles. So they had some slight degree of movement on the land. Over millions of years some of them adapted to like in rivers rather than the ocean, and sometimes crawl between smaller bodies of water. Hence their flipper adapted to be flipper-feet.

One plant can't be super-efficient at everything. Think of it in terms of where the plant is spending its resources. It is gaining energy from the sun (photosynthesis) and taking in carbon dioxide, water, oxygen and nutrients from the air, ground water and soil. It then has to allocate those resources to doing various things. For instance: Get bigger to ...

Yes, if your civilization has done a few things over the course of its history. The rodents are domesticated. Your people have been breeding them for centuries. So like modern pigs, modern chickens and modern cattle, they have been selectively bred to grow fast (deliberately or accidentally). They therefore no longer resemble their wild ancestors in terms ...

Inherited immunity. The longer you walk the earth, the more diseases and antigens you encounter, and the more experienced your immune system gets. When a baby is born it gets immunoglobulins from its mother and so for a short while can benefit from the protection of her experienced immune system. Then after a month or two the maternal immunoglobulins wear ...

This will be a massive undertaking, and is probably not economically viable enough. As other answers pointed out, saturation the entire atmosphere with nutrients is near impossible, and a gigantic inefficient waste. But even if it can be done, this will not negate the need for food production, as the nutrients will still need to come from somewhere. This ...
