Compared to humans, why can some animals jump many more times their size? I'm thinking of cats here which apparently can jump up to seven times their length. From a physics standpoint, what would be an approximate answer to this, and how would determine it using scaling arguments?

Hi, All: I've been curious about this for a while: Why are there different names for different groups of animals? We have ( I think) schools of fish,packs of wolves, etc. I imagine it may have to see with the fact that groups of animals are organized differently. Still...

We're in the Kingdom Animalia, but are we animals? Or does the Animalia Kingdom include humans and animals?

I was curious, why is it that dogs will live somewhere in the 10-20 year range, but humans make it to 80, and animals vary so much?

How would they look like? Being more specific and less speculative: would higher atmospheric pressure (ex. 5 atm) mean that it is easier to fly/glide because lower wingspan would allow to achieve the same lift? Or it would be actually harder, because denser atmosphere would mean higher drag...

Are neurons in humans different of the ones of other animals like spiders for example? In other words if one shows you a neuron under the microscope, can you identify from which animal it comes from?

Why are women more brightly "colored" (whereas in other animals males usually are)? So, possibly I'm looking for the explanation according to Richard Dawkins, but I'd welcome all points of view. Why do women dress more brightly (when men still do the courting), while in other animals the sex...

Does anyone know how I can find out which animals have a pre frontal cortex and which do not? I am interested becuase I came across a claim that seems highly suspicous printed in a book by a philosopher named Michael Murray. He claims animals have pain but they are not aware of their pain...

This is sort of an alternative to the 'would you eat cultured meat' question. What if we could engineer animals without conciousness (sentience)? Would it be cruelty free? Would you eat it? Example: http://www.wired.com/underwire/2012/02/headless-chicken-solution/ I find it terrifying in a...

When we moved from Los Angeles to Oregon, we were challenged to understand the attitude that many people around here have about animals. After a time we began to understand that it goes back to farming. Farmers often view animals like cats and dogs more as farming implements or cattle, rather...

Hi I'm not a biology or science student. So, please keep your replies in plain and straight language so you could be understood. Thanks. Do animals and birds also become unconscious during their deep sleep like humans? Among humans the extent to which one is absorbed in one's sleep varies...

I have observed that the animals and birds have a kind of idea that humans' face (and eyes) is a primary front to observe the world around them. If one has his back toward the bird, then the bird won't feel that uncomfortable. But when you stare at an animal or bird, it becomes shy or afraid and...

Say everyone in the world suddenly became vegan (eating no animals products whatsoever). How would we take care of the domesticated animals (those that cannot survive without humans)? Not all animals can be used for work. There are 1.3 billion cattle, 2 billion pigs, 24 billion chickens, and 1...

In the future, will it be possible for humans to transform into other animals via genetic engineering?

Animals which attack their "cousins" Besides humans, what are the most advanced animals to attack their own species because of dissimilar genetic traits - e.g., racism, disability bias or sexism. Could this be explained in terms of natural selection?

This is a show on National Geographic. It's a group of "tough guys" that are real softies when it comes to animals. They go to great lengths to rescue animals and see that they are given proper medical care and humane treatment. Just a great show and an extraordinary group of people. Watch...

Why do some people love "connecting" with animals? I was just watching a series about a man who lives among wild bears. While this is a bit extreme, I can appreciate the desire to "connect" with other species. Why? No, this is not a trick question. I just don't see any particular reason why...

I've always been curious about the answer to this question. Can anyone point me to some research regarding this subject matter? Have we made any advances on finding out the answer to this question? I am assuming that it would be pretty inefficient, and toiling on the body and brain to be active...

Many people think of animals as stupid and capable of learning only through conditioning without the ability to make creative leaps. My question is are there any instances where an animal has tried to train a human successfully? Most human would be to blithe to even entertain the notion that...

If a turtle and beetle fall from the same height, which would sustain more injury? Assume that both the turtle and beetle are geometrically similar. The amount of force of which the creatures reach the ground would be the measured parameter, right? So, including air resistance in the equation...

Does anyone know a site that shows what species of any animal is in an area. Ideally one that would picks states, countries, or zip codes. I'm just interested in knowing about what animals are around me and identifying them. Thanks in advance.

I remember reading somewhere that animals do rape each other sometimes. One of my friends told me that she didn't think animals could rape each other. She said, "Animals don't have the notions of consent that humans do." Do animals rape each other?

There is supposed to be a switch of magnetic poles in several thousand years which already started 150/200 years ago. This gave me an idea. Can the changing magnetic orientation cause the whales (and other large mammals living in the sea who use the Earth's magnetic field) to "crash" on shores...

Hi guys, Some background : I'm in the early stages of my first semester of High School Biology and I'm already having some problems coming to terms with the basics. Our original teacher was in car accident over break so we're stuck with a sub, who's a spanish teacher and completely hopeless...

Homework Statement A wooden rod of negligible mass and length 85.0 is pivoted about a horizontal axis through its center. A white rat with mass 0.500 clings to one end of the stick, and a mouse with mass 0.240 clings to the other end. The system is released from rest with the rod...

Hi, Cold blooded animals don't produce body heat to keep themselves warm. Why is this? Is their metabolism more efficient (produce more ATP rather than heat)?

Just curious, does anyone here do any animal breeding and make a profit from it (or at least make enough to cover expenses for the hobby)? What sorts of animals have you bred? How much fun is it? How much work is it? How much of a profit can you make with different animals?

Homework Statement The posture of small animals may prevent them from being blown over by the wind. For example, with wind blowing from the side, a small insect stands with bent legs; the more bent the legs, the lower the body, and the smaller the angle . The wind exerts a force on the insect...

I can't find the right words to describe this story. "Idiotic", "stupid", "ridiculously irresponsible," don't even do it justice. http://www.sun-sentinel.com/news/local/miami/sfl-727cougar,0,2400832.story
