To heck with the spider,although neat and ever seeing.Check out the exo-skelatons.

I will have to support Evolution! Let me give you a definition of Evolution!\nBiological evolution, simply put, is descent with modification. This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations).\nDocumentation of ancestor-descendant relationships among organisms also comes from the fields of biogeography, taxonomy, anatomy, embryology and, most recently, genetics — particularly DNA analysis.\nThe fossil record remains first and foremost among the databases that document changes in past life on Earth. Fossils provide the dimension of time to the study of life. Some of the most basic observations about fossils and the rock record were made long before Darwin formulated his theory of “descent with modification.” The fossil record clearly shows changes in life through almost any sequence of sedimentary rock layers. Successive rock layers contain different groups or assemblages of fossil species.\n{We have now more than enough fossils to determine for sure that humans didn’t appear on this planet in the genetic form they are today!\nWE HAVE MORE THAN ENOUGH EVIDENCE THAT THERE WAS AT LEAST ANOTHER SPECIES WHICH LIVED WITH US!! And I am talking about Neanderthal man who was not our ancestor but a different Human than us!!! (Did God experiment with human species?) We even have proof that at a certain point in time 3 human species shared the planet! (Homo sapiens, Homo Erectus, Homo Neanderthals)}\nOf course I want comment the stupid argument why all the apes didn’t evolve to humans. Ok I will comment!!\n(We share a recent common ancestor with chimpanzees and gorillas; we have many anatomical, genetic, biochemical, and even behavioral similarities with these African great apes. We are less similar to the Asian apes--orangutans and gibbons--and even less similar to monkeys, because we share common ancestors with these groups in the more distant past. \n! By the way why God decided to create 5 different species of primates and 280 different species of monkeys?)\nAs a conclusion Evolution is not a theory but a proven fact (In scientific terms, "theory" does not mean "guess" or "hunch" as it does in everyday usage. Scientific theories are explanations of natural phenomena built up logically from testable observations and hypotheses. Biological evolution is the best scientific explanation we have for the enormous range of observations about the living world.) Creation is a Hebrew Myth and unfortunately is not a fact but a myth!!!!

Arachnids include the spiders, scorpions and their relatives such as pseudoscorpions, camel spiders, whipscorpions, mites and ticks, and daddy longlegs.\n\nThis is a highly diverse group, that ranges in size from tiny pseudoscorpions that are nearly microscopic up to the gigantic goliath bird-eating spider of South America that can ten inches across.  They live in almost every habitat on Earth, including Antarctica, the Sahara desert and everywhere in between.\n\nEach species has its own ecological niche, with its own predators and prey.  So there isn't any single 'main predator' on arachnids.  Each species would have its own position on the food chain.

Maybe it's a spider-human hybrid. That's the only way to get a criminal animal!\n\nOK, bad joke. \nThey're several species of tiny spiders from Australia, South Africa, and Madagascar, that unlike other spiders\ndo not build webs; rather they hunt other spiders with their elongated (and quite impressive) chelicera.\nThey've been mentioned because recently nine new species were added to the family.

I'd like to think that you're asking this question with an earnest wish to get good informative answers. If that is the case, I invite you to see the link that Kurdiatcha left, or to do a web search for the term, or else, to read some good Evolution textbooks such as Ridley's "Evolution" or Freeman & Herron's "Evolutionary analysis", or Futuyma, or Stephen Jay Gould if you want something more entertaining.\nIf that is not the case, I'm not bothering anymore *sigh*

Go to your biology book and look it up or go to wikepedia

I think one recent cave discovery was in Algeria I think, or somewhere in Africa.  In the cave, they found a new species, whick looks like a spider,scorpion, and probably a cricket, i forgot the last one.  Anyway, that was one of the recent cave discoveries.

It's hard to tell from your description (which doesn't include where you live, for example) what the spider might be. Odds are it is NOT poisonous, since there are very few spiders that are poisonous - if you are in the US there are two and one of them is not brown. If it is an orb weaver as you describe it is quite harmless and could be carried (loosely) in your hand to a bush without fear of being bitten.\n\nCan I suggest asking someone who is not afraid of spiders to take the spider out of your car (getting it into a cup is the easiest way to handle them without hurting them) and put it somewhere it will be able to live (not the middle of a parking lot).\n\nIt's interesting that despite your professed fear and hatred of spiders you've spent a fair bit of time examining this one and are interested in finding out what it is - all indications of a possible future arachnologist :-)

Yup and so are spiders scorpions and crabs, They all have the same exo-skeleton, and the same amount of legs   8    That puts lobsters, scorpions, crabs ,spiders, ticks and???No one knows for sure  all in the same family, BON APPETITE"

I can't find anything, but I don't know what I'm looking for other than a black and yellow spider.  Here's a source which has some good pictures for which you can possible identify.  Check the garden spiders, orb weavers, and banana spiders.\n\nhttp://www.spiderzrule.com

a crawled or "spider" is a SW that running on the internet to collect information about sites on the internet. \ni think there is some free "spiders" you can used, so try searching on google and you will find something usefull.\n\nbest regards...

How did evolution change over time? You mean...how did evolution evolve?  Heh.  The evolution of evolution.  That's funny.

Depends on the spider.  Something like a tiny money spider, barely larger than a 12 point font period will not be able to lift nearly as much as a goliath bird eating spider the size of a dinner plate.  \n\nThe spiders are very diverse group, and so there is no easy answer to this question.  Some are robust and hearty, like crab spiders, and built for physical strength to capture and subdue their prey.  Others are thin and spindly, like the long-jawed orb weavers, and depend on their webs and venom to finish of their prey, rather than physical prowess.\n\nAlso, few spiders are built for actual lifting.  Some are very good at dragging heavy objects (like trapdoor spiders, but few of them can go up to an object, pick it up and lift it over their heads, regardless of how physically strong they are.\n\nIn terms of physical strength compared to body mass, many spiders can drag or move many times their own body mass, but the exact proportion depends on the size of the spider and their particular build, there is no set ratio.  In general, small creatures like insects and spiders seem to have incredibly high strength proportional strength, but that's mostly due their small size and the cubed-squared revenge proportions between surface area and volume as things increase in size.\n\nFor example, say an insect weighs 1 mg, and has the strength to lift 10 mg:  That's ten times its own body weight!\n\nIf you double the size of the insect (twice the height, twice the width, and twice the depth), that insect doubles its strength so it can lift 20 mg, but it now weighs 8 mg.  Now the insect with the same proportions can only lift 2.5 times its own body weight.\n\nDouble the size of the insect again, and it can lift 40 mg, but because it is twice as long, twice as thick and twice as deep as the 8 mg insect, the bug now weighs 64 mg!  The insect can no longer even lift its own body mass, and is unable to move or support itself!

A good place to start is the talk origins site (http://www.talkorigins.org/ ) which puts together a lot of the stuff that originally appeared in the talk origins usenet group.  Most of it is focused on exploring the creationist/evolution controversy, and sometimes takes up a defensive stance when none is required, but generally gives a good overview and explanation of many central questions in evolution.\n\nThe site for the PBS television series 'Evolution' (http://www.pbs.org/wgbh/evolution/ ) is also a very good site.  The related web activities for each episode's page give incredibly good basic information, and the Teacher's Guide section could easily form the backbone of an entire High School level course on evolution (not that any High School actually offers such a course).\n\nIf you can get a hold of the Evolution series itself, it also provides some excellent explanations of many of the concepts.  It may be available through your local library.\n\nAnd the University of Berkeley's Understanding Evolution website is also an excellent resource (http://evolution.berkeley.edu/ ).  \n\nThose three sites should keep you busy for the next few months.\n\nGood luck!
