Evolution

The largest domestic duck breed is widely considered the Muscovy Duck. The can get up to 15lbs and were introduced into Europe in the 1500s. They originated from Central and South America. The ducks are also considered rather aggresive

Alligators us camouflage and not mimicry because if they mimicked they can go some where and turn into that color of area

organic evolution is thus the progressive development of animals and plant from ancestors of different forms and function

Some adaptations include, opening and closing the stomata in hot and dry weather to prevent losing Carbon Dioxide. Other adaptations include preventing water loss, for example, cuticles were there to provide a waxy layer to prevent dissication, trichomes which are extensions on the leaf epidermis that help to break up the wind and reduce water loss. Another example is the use of lignin, which is used to help support plants against gravity. Last example, is that plants need to avoid being eaten, so one adaptation is by producing poison to avoid being eaten by predators, or something like making you itchy when you touch the plant (poison ivy).

hoped this helped!

Mammals came before birds. The first mammals lived in the Triassic and the first birds lived in the Jurassic.

It is inaccurate to say that humans were once other similar apes such as gorillas or chimpanzees. Instead, evolutions states that our species and other species of great apes share a common ancestor. That means at some point a long time ago, our three species were one species and over time, we diverged into what we are today. It is exceedingly unlikely for any of the current species of great apes to retrace millions of years of evolution back to that common ancestor and begin to evolve on the exact same path as humans. Instead, they will continue on their own evolutionary path that is parallel to others and will not converge.

Ornithischians with a hip structure similar to that of present day birds.

The humans evolved in 2000. They evolve if they visit other planets and survive without air. They evolve into a 7 foot tall green creature.

The ancestors of dinosaurs are bacteria. they would split and reproduce by itself and creating multiple cells until you had a larvae like dinosaur.

Other scientists say either they started as the "Big bang" or molecular forms that grew.

so technically there are no ancestors of dinosaurs only decendants

I think it may have been Margaret Mead

In a strong sense, you're right to ask this. It's likely that modern birds evolved from theropod dinosaurs. Recent fossil remains of velociraptor have proved that they had feathers and wings, an expert said that if velociraptors were found alive today then we'd probably think they were odd looking birds. Some biologists think that birds and theropod dinosaurs should be classified in the same group, although no modern bird has teeth which theropods (which includes T. Rex) had in spades, so the classification might have to a little looser to include them all.

So, you've a strong case to say that the dinosaurs didn't completely disappear - they're still here as birds.

Dogs are alive b/c they want to be alive and also b/c god put them here to protect b/c, again when 2012 hits there are going to be some big changes and we will need them to help us stay alive and keep us protected.

No, man did not descend from apes, at least not the modern apes that we know. However, there is overwhelming evidence, both from the fossil record and from DNA, that man is descended from the same common ancestor as the apes. Our ancestors diverged from the ancestors of chimpanzees around seven million years ago.

The first step involved the lobed fined fishes, which could travel in very shallow water or possibly in mud. They were a response to very heavy predation.

The second step involved the lung fishes, which could use air directly without needing to return to water to use their gills periodically.

The third step was true amphibians.

Chameleons have existed for at least 26 million years. That is how old the oldest fossil record shows them, but they are believed to have been around longer than that. A fossil ancestor to this clade of animals dates back some 100 million years.

For the same reason that fish, insects and spiders etc also lay large quantities of eggs. To ensure the survival of some of their offspring. The eggs and young are usually left unprotected and many will perish, by laying large quantities some are likely to survive and reach maturity.

As far as we know now it is. There is ample scientific evidence to support it. Some ask, "if we evolved from monkeys and apes, why do we still have monkeys and apes today?" Eugenie Scott (head of the NCSE) responds that that question is equivalent to, "if I descended from my cousin, why does my cousin still exist?

In answer biologists explain that you did not descend from your cousin, but that you and your cousin share common ancestry. Similarly, humans and the other primates (tarsiers, lorises, monkeys, apes) appear to have evolved from a common ancestor.

Natural selection acting on the available genetic variations within a species creates variations according to the needs and selection pressures in a particular environment. This can create a large amount of variation in a relatively short time such as in all the dogs, together with jackals, coyotes and wolves, which are all interfertile, yet which appear quite different in many ways.

We know the earth is billions of years old because we have accurate dating techniques that reveal that fact to us. Long lived isotopes, such as Uranium 235 and 238, Thorium, and Potassium 40 have half lives measured in millions and billions of years. The ratios of parent to daughter isotopes in decent samples reveals the time at which the rocks containing these elements were formed.

On every continent we have found fossils of dinosaurs (including Antarctica). And on every continent where we have found dinosaur fossils we have also found volcanic ash strata above and below those rocks--not always where we find dinosaur fossils, but fortunately often enough. The reason this is fortunate is that volcanic rock can provide absolute dates using the aforementioned radioisotopes that yield good estimates for the fossil bearing strata. Everywhere we have done this (and reliable dates have been obtained many hundreds of times) we have NEVER dated dinosaur fossils less than about 63 million years, or more than 250 million years old. The cretaceous/tertiary boundary has been accurately dated on all seven continents to about 65 million years ago.

The oldest fossils we find are of single celled marine organisms. Stromatolites (bacterial mats of aquatic colonies) have been dated to more than 3 billion years ago. So for several billion years earth's oceans teemed with single celled organisms while its land surface remained barren. A little over half a billion years ago we find the first multicellular organisms, still all in the oceans. Nothing on land. In the Silurian vascular plants first make their way on land, and primitive insects. Within a dozen million years or so we find the earliest amphibians, bearing uncanny resemblance to devonian lungfish. The tetrapodal structure of these earliest land animals is inherited by all subsequent terrestrial vertebrates, up until some reptiles (snakes) lose their limbs.

Nothing about the theory of evolution violates any physical laws, contrary to what some misinformed individuals may claim. Otherwise, scientists would readily reject the theory. In addition, nuclear physicists didn't simply invent evidence for an ancient earth to satisfy the needs of paleobiologists--they came by that evidence most naturally. Even before radioisotopes, however, earth scientists had worked out very closely the ages of the cenozoic, mesozoic, and paleozoic periods using well understood geological processes.

Finally, nothing about the theory of evolution denies the existence of God. It was widely believed, before Copernicus and Newton, that the planets were pushed about their orbits by heavenly hosts of angels. Newton's theory of gravity did not disprove the existence of angels any more than Darwin's theory disproves the existence of a Creator.

comoscow would like to know more about the evolution of computer system because it don'st really sound very clear to me.

mearkats live in a desert type area and their water is supplied by the larve, scorpions, and bugs that they eat in the wild. Animal channel had a real good series on the mearkats and how they live. If you have a zoo exibit for them, I believe that you should give them as close to the type of food and environment that they would live in ( in the wild) . The purpose for having animals in a zoo should be to help keep these beautiful creatures breeding to help keep them alive and not become extinct.

Actually speaking electronic data processing doesn't go back more just half a centurti.e. they existence merely 1940's they very first modern electronic computer became operational only in early 1940's. Infact, its only a little morethan just five decades ago since the first modern electronic computer was brought in to existence for the purpose of bussiness data processing. Computer before that were only used in scientific and technological field.
