I mean, it seems like common sense to walk. But how do we do it? How can we suddenly get such good balance on two feet? And why are there so many different ways of walking? What's the best way to walk (e.g. coolest, most professional, most efficient)? How do you walk?
Thanks, and sorry I have to say this, but if you're going to answer, post a real answer and not an insult.

Consider the facts: crop yield can be increased, and flavor would be increased. But, in some cases, they can be allergic or mutagenic (can cause mutations).

blackbird. I put a eartworm in the palm of my hand and the blackbird hoped over and took it. Is this normal behaviour for a blackbird? I live in the countryside

For all the animals that went into outer space, why is it that the BIRD was the only animal that died?

What is really a fourth dimensional?..If a body can tracel at a speed of light, the mass of the body increases; we know that the air resistance is more with the increase in size of the object, hence is the theory of relativity valid in normal life?(other that in a vacuum space)

I recently relocated to Puerto Rico, and while on the north-eastern coast, at a restaurant, I spotted a pair of mammals, larger than a squirrel, but smaller than an otter. I believe it to be amphibious. It was dark brown (almost black, as it also looked wet), with a large hairless tail, like a rat, but was NOT a rat. Can anyone help identify this creature? Lead me to a website, to see photos? One person in my group suggested it was a 'Puerto Rican Squirrel', but my investigation has shown there are no such creatures here. I do know that mongoose where brought here many years ago, to help with rats in the Suger plantations, but both are long gone (rats & mongoose).

It is black, with four symetrical creamy white markings on the sections nearest its head (which looks like its bottom!!) and a small creamy white spike near its bottom (which looks like its head!!) It is about the length of my middle finger and about 1 1/2 times as wide. It was found in a garden in Surrey today. We have not seen anything quite like it and wonder if anyone has any sensible suggestions?
