Question	—	How could my humanoids metabolize smoke? I have a species of humanoids that spends a lot of time around fire. They are able to spark their own fires, and they have a reasonable fire resistance. One problem presenting itself is smoke inhalation. These humanoids are genetically engineered, so evolution isn't a problem. They don't have to w... (more)	—	about 6 years ago
Question	—	How could my humanoids have fire resistant hair and skin? Explanations for fire setting are easier to come by than explanations for fire resistance. Being able to set fires with nothing more than their hands, my 'fire-setters' need protection from the flames. So far, traits such as bony/keratinous plates or lots of protective skin would change the physiqu... (more)	—	about 6 years ago
Question	—	How could intelligence be balanced with a large muzzle? My species of caniform-like creature has a relatively long muzzle because of its strong sense of smell. I would like to know how to give it a long muzzle with its large brain size. Members of this species primarily communicate with each other through certain electromagnetic waves, bodily scent, and o... (more)	—	over 6 years ago
Question	—	How do I change the color of my alien's feces? I apologise in advance for the graphic nature of this question. I guess it just had to be asked. I am looking for a way to make the feces of my alien vertebrates some color other than brown or green. In our Terran vertabrates, bile that is broken down in the gut along with items in the diet affect ... (more)	—	over 6 years ago
Question	—	What evolved weapons could be used against graphene skin? Life had been good for a certain class of tetrapods. They evolved two layers graphene in a specialized collagen creating a relatively thin yet seemingly impenetrable hide. All of their natural predators moved on to other prey without such tough skin, but soon over competition for plants struck. Many... (more)	—	over 6 years ago
Question	—	Would this biological cooling system work? I'm working on a class of tetrapods similar to mammals with warm blood. I am planning for their metabolisms to be quite high on average, among the carnivores especially. They range in size from two grams to twenty tonnes. In reality, birds are some of the warmest animals with body temperatures aro... (more)	—	over 6 years ago
Question	—	Would graphene be an effective substitute for collagen in skin? For my group of alien tetrapods, I would like to have them evolve a sort of built in protection against the elements and other organisms. While researching, I came across information on graphene, and it seems like a promising material to incorporate into living creatures. They are built with and req... (more)	—	over 6 years ago
Question	—	What would be a more efficient reservoir for biological hydraulics? This is part of a series of questions about biological hydraulics, the fist one being here. My tetrapods have hydraulics in the thighs of their hind legs. To push or pull fluid from closed chambers in the legs, muscles are going to contract either in the legs themselves or the abdomen. As hydraul... (more)	—	over 6 years ago
Question	—	Would biological hydraulics be worth evolving in tetrapods? I am working on an extraterrestrial class of tetrapod-like organisms. To give them an evolutionary advantage, I am considering biological hydraulics to supplement the muscles in the hind legs. Eventually I may ask about more mechanisms, but currently, I am investigating whether or not this would ev... (more)	—	over 6 years ago
