Why There Are Still Apes
- Many people believe that man did not evolve from apes at all, we were created by God in His own image. That God gave man a human soul that makes them individual.
- The only other option is a theory called evolution, by which over billions of years, the whole earth and everything in it was formed by hydrogen, which spread through the universe at the Big Bang, an explosion in which the hydrogen was formed.
- Human beings (homo sapiens) related faintly related. Humans and other apes might share a common ape or ape-like ancestor.
- A species only evolves to help it in its survival. The apes' ancestors could survive being an ape so they didn't continue to evolve, whereas our ancestors kept evolving to help them stay alive. Survival of the fittest is what drives evolution, and our ancestors just happened to "need" evolution more than the apes. Evolutionary process is performed by mutations, which are usually harmful or fatal. For evolution to occur, an incredible chance happened so that the mutation would not harm or kill the new creature.
- Apes and humans evolved from an unknown common ancestor. This ancestor split up and evolved into different species, one became erect and the other continued as it was.
- Humans didn't evolve from apes; rather, we and apes evolved from a common ancestor (who is no longer with us, we have no fossils proving this fact, but we believe it anyway). The relationship is more like cousins than parent-child.
- By a very great chance, humans developed a brain that allows them to think, love, and be individual persons. Christians call this a soul. It elevates us above beasts.
- There are still apes because some apes did not evolve into people. If rocks are crushed into stones, why are there still rocks? There are still rocks because some rocks did not get crushed into stones.
- Different species have evolved according to the conditions and ecological niches they find themselves in. Speciation occurs when a subtle change confers an advantage on a given population.
- It is also important to remember that not all changes of animals mean it has evolved. Animals have great genetic variety, to suit different environments. This is called natural selection. Let's think of a simple example of changes by natural selection: If the world were suddenly covered in snow, and polar bear-type predators invaded everywhere, it stands to reason that they'd be more likely to eat dark-colored animals which they could see more easily. That would give an advantage to animals which, by chance or design, happened to be white. Animals of a usually black type which happened by chance to be *partly* white might also escape the bears. They would then be most likely to breed, passing on the white genes to their offspring. Over time, through breeding in a selective group, all animals would become white, as the ones least suited to their environment were weeded out. Some species which were unable, by chance, to adapt, would go extinct as the polar bears ate the lot of them. So, humans have evolved in a different way than chimps, gorillas and orangutans because the requirements of the environment we found ourselves in were different. It was an advantage for us to go in the direction we went, just as it was for the other apes. Evolution works randomly. Natural Selection works towards the animal's specific needs. The mutation to create more hair in a cold environment would be in a specific population so some humans in the group would have more hair by nature (genetically). These individuals would in turn have a greater chance for survival in the cold environment. As they are selected for by nature their percentages will increase. More of the hairier humans will survive to reproduce and their children will be genetically driven to be hairier. That is just one of the marvelous and logical ways evolution in our nature world occurs.
- Natural selection is variations in genetic genetic variety that changes a species within itself. For instance, say a tribe of fair skinned people traveled to a very hot climate, those people with darker skin would be more likely to survive thereby passing on there dark skinned genes and eventually weeding out the fair skinned people.
- Evolution only occurs when it is necessary. Some apes evolved into man because either they moved to a new environment or their existing environment changed, making evolution necessary for survival. So, the apes who needed to adapt to their new environment through evolution to survive either did so or were wiped out (apparently, they changed, creating the human race), or stayed in a friendly environment, making evolution unnecessary and therefore, nonexistent (the apes in these conditions remained apes).
- Technically, humans are apes.
- Science never said humans evolved from apes. Science said that humans and apes evolved from a common ancestor. That makes humans and apes related species. And those who abhor the idea of humans evolving from apes may be even more incensed to learn that we did not evolve from apes, but from a more primitive species.
Possibly one for the physicists. But I think air resistance has nothing to do with it. I think gravity is what saves us. If you look at liquids in a weightless environment (there is air resistance)it just floats around, which means it can easily be inhaled and you would drwon. Air resistance prevents a falling object from reaching the full speed produced by the acceleration of gravity. It keeps falling raindrops from reaching bulletlike speeds. If air resistance were not present, raindrops would gain 10 meters per second of speed for every second of their freefall and thus reach the ground at dangerously high speeds�perhaps fast enough to puncture your skin. Not true, "The more compact and dense the object, the higher its terminal velocity will be. Typical examples are the following: raindrop, 25 ft/s, human being, 250 ft/s." I hardly think a raindrop falling at 25 feet per second is going to do much damage. Answer #2 is true. There is no "terminal velocity" without air resistance. Terminal velocity occurs when the force of air resistance is balanced against gravitational accelleration. The object continues to fall but at a fixed speed. Without air resistance, the object will fall faster and faster without bounds until a dangerous velocity is reached.
The last ones name was Katrina. To find out the wrest of your questions look on the "NOAA" web site. It will tell you everything you want to know. I believe the most storms in one season was 19 named storms, but not all were hurricanes. Nitro... thanks for the reply. What I meant was not the most recent hurricane (Katrina) but the name of the highest numbered hurricane in a season - which according to this snippet from CNN.com was "Wilma." ---------------- http://www.cnn.com/2005/WEATHER/09/08/tropical.weather/ ---------------- ... Just a week into September -- historically the most active month for tropical activity -- the 2005 Atlantic hurricane season has seen 15 named storms, six of which reached hurricane strength with winds of at least 74 mph. Four of those became major hurricanes, with sustained winds of at least 111 mph. According to the National Hurricane Center, the historical averages for a hurricane season are 10 named storms, six hurricanes and two major hurricanes. Those numbers have been met or exceeded this season, which doesn't end until November 30. The largest number of named storms ever recorded was 21, in 1933, a record that will be broken if just seven more storms develop in the next 12 weeks. And if that happens, the hurricane center will run out of names for the first time since it adopted the system of assigning names to storms in 1953. The letters Q, U, X, Y and Z aren't used, because few names begin with those letters; the 21st and last name on this year's hurricane list is Wilma. After that, Greek letters will be used to designate storms, beginning with alpha. The most hurricanes recorded in the Atlantic is 12, in 1969, according to the hurricane center, and the largest number of major hurricanes is eight, in 1950. ###
A basketball depends on pressurized air for its bounciness. When the ball hits the court, it compresses that air and the air stores energy in its compression. The ball's rebound is powered by the air returning to its original characteristics. The ball's skin, on the other hand, isn't all that bouncy and doesn't store energy well. To bounce well, the basketball needs to store energy in its air during the bounce, not in its skin. That's why it's important to have an air pump so that you can keep your basketball properly inflated. When you cool a basketball, however, you reduce the pressure of its air. That's because the air molecules have less thermal energy at colder temperatures and thermal energy is responsible for air pressure. A basketball that was properly inflated at warm temperature becomes under-inflated when you cool it down. At the same time, the basketball's skin becomes less elastic and more leathery at cool temperatures. So the basketball suffers from under-inflation and from a leathery, not-very-bouncy skin. If you cool a basketball to low enough temperature, its skin will freeze and become brittle. Just how low the temperature has to go depends on the material used in to make the basketball. I've never seen a basketball shatter on the court, even in pretty cold weather, so I doubt you can "freeze" one in a household freezer. But I'm sure that a dip in liquid nitrogen at -395 °F would do the trick. I often freeze rubber handballs in liquid nitrogen for my class and then shatter them on the floor. when it hits a surface it is compressed, the molecules inside it are pushed closer together, and then they repel each other causing the softball to bounce.
