why do we have toes on our feet
What's your favorite part of your body? For some, it's their, because they allow them to see the world around them. Others couldn't do without their, because they love to listen to music. Many people would probably say their tongues, since they bring the tastes of delicious foods to life. On the other handвor, not many people would claim that their toes are their favorite body part. Why not? Some might point to the fact that they're dirty and
from time to time. Others might point out the fact that they don't seem to be all that useful. Do toes even do anything? Why do we have them? Do they serve any?
Could we live without them? These are all things many people might WONDER about their toes. Rest assured, you need your toes. In fact, they are quite. Even though we can't use them to cling to tree branches or pick fruits, like can, our toes serve a few important purposes. For example, your toes provide and when you. When you, your toes maintain contact with the ground about 75% of the time. They exert in a manner similar to the bones integral to movement. Your toes help your feet to the of your body when you. They play an even more important role in running. When you use your whole while, your toes effectively increase the overall length of your, allowing you to run faster.
Of all your toes, your big toes are the most important. They play the most critical role in your. They also the most when standing. Your big toes can almost twice as much as the other toes combined. The least important of your toes are undoubtedly your pinky toes. As the smallest toes, they the least and have the least on. People born without pinky toes or those who lose one in an will see very little, if any, changes to how their feet. Of course, all these uses for toes shouldn't overshadow one of the fun uses for toes: tickling!
If you have a friend with toes, you know how fun it can be to tickle them and send them into peals of! Answer 2: Well, when evolutionary ecologists want to answer a question like that, we start by looking for patterns, like: who has toes and who doesn't? If we look at mammals (animals that give milk to their young and have hair), the only ones I can think of that don't have toes are marine mammals like dolphins and whales. This means that it would be odd NOT to have toes unless there were a really good reason to lose them over evolutionary time. Marine mammals don't even have legs except for tiny leg bones deep inside their bodies.
Clearly, having a tail as a water propeller works better than kicking with legs. Our toes don't cause us any problems, so we wouldn't expect to lose them, but are they important to us? Most primates (such as monkeys and chimps) use their toes to grab trees. Obviously, ours aren't good for that. Do they help us walk, run, and jump? I think they help to stabilize us and help us push off the ground, but judge for yourself. The branch of science that looks at questions like that is called "biomechanics". These scientists look at movies and computer animations to study how we move and related issues, like "What's the best way to throw a ball? " For a computer animation of a runners, gymnasts, etc. , go to http://www. cc. gatech. edu/gvu/animation/. (You can "cut and paste" the address. ) Another simulation of walking can be found at http://www-personal. engin. umich. edu/~artkuo/Passive_Walk/passive_walking. html.
Just click on the picture. How do the toes fit in? NASA has some really cool visuals of the human body, but if you're easily grossed out by bones and such, don't go there: http://biocomp. arc. nasa. gov/home. html
