Evolution

variatio brings about evolutionary change with in species as over millions of years the have to adapt to the ever changing habbitats. take the horse for example millions of years ago it used to have multiple toes.yet over millions of years it has evolved to only have one toe

Any compound with elements C,H,O are called organic compounds. SO Carbon helps make organic compounds. Examples of polymers that are made of these elements are Polysaccharides, Proteins (with N and sometimes s and p), Nucleic Acids (DNA, RNA), and although not a polysaccharide, Lipids (Fats, oils and waxes) Each of these biomacromolecules are important in biology...if you know the important of these then you know the importance of Carbon...eg. Polysaccharides for energy, engergy storage, structural, Lipids for insulation, fat storage, water proofing, Proteins for Structure, hormones, enzymes, Nucleic Acids to code for the synthesis of Proteins and carrying on genetic information on to the next generation.. Hope that helped.

People often think of evolution as what they call survival of the fittest. However, that means a fight among members of a species. This is not what is really meant.

The 'fight' is with the environment and the species and not a fight of one individual with another.

If the species has a way of best surviving what the environment throws at it, it will survive. Other species might not and will die out.

A: More offspring are produced within a population of a species than can generally survive. B: More offspring are produced within a population of a species than can generally survive.

C: Some individuals possess features that increase their probability to survive compared to individuals lacking these features. D: Some individuals possess features that increase their probability to survive compared to individuals lacking these features

Individuals in a population of a species vary in many ways Individuals in a population of a species vary in many ways

Changes in the environment cause beneficial mutations.

Fossil

This theory states that the organelles found in cells were once their own independent cells. Throughout time, these independent organelles were consumed by bigger cells and not digested, but used in exchanged for their services.

My sheit!

Design!

I'm not actually sure but I think it has something to do with the whole 'supernatural' thing and the fact that it is called 'supernatural phenomena' is because some dude decided that it was not real and therefore unnecessary to be looked into deeper. I mean vampires and werewolves and all of that are under the banner of 'supernatural' and you don't believe they're real do you? what is the point of looking into something that has already been "proven" not to exist. it's not likely you'd believe me if I said I were being haunted by the ghost of some person.

Transitional fossils are important because they are visual evidence of one type of animal evolving into another type of animal. A transitional fossil always contains features of one type and features of another.

For example, Archaeopteryx is a transitional fossil that is a cross between a dinosaur and a bird. It has a bony tail, teeth, and claws like a dinosaur, but it has feathers and is able to fly like a bird. It is an important link in the evolution from dinosaurs to birds.

Put simply, it doesn't. There really is no other reason, any archaeologist, paleontologist, geologist, or other professional in a field of artifact study will tell you that there is no "line" of creatures leading up to today's animals. For example humanoid skeletons where found conspicuously at the beginning of the Cambrian period and at no time before then, the only explanation for this is that an unaccounted for variable such as a "supernatural force" was present and not noticed

Ayer's Rock/Uluru is a sandstone formation in the centre of a desert.

Rocks are the area of geologists, not biologists. Evolutionary scientists wouldn't care either way about it (unless it happened to contain some new fossils or biological research material).

Phylogeny is the evolutionary history of a particular group of organisms or their genes. Phylogeny can be represented in a phylogenetic tree which graphically represents the lines of descent among organisms or their genes. Learn more at 23andme.com.

natural selection!

All reactions, even exergonic, need an activation energy to happen. Enzymes provide that activation energy. Sometimes by their R groups, sometimes by stressing bonds in a molecule in their activation site and sometimes by only providing a space apart from the cytosol in their activation site for two substrates to react.

Fossils can be used as evidence for evolution because they can show the development of a species over a long period of time.

lizard The common ancestor of all modern tetrapods looked like a fish that had nubs the became limbs through evolution.

The evolution of aerobic organisms depended on a metabolic product of cyanobacteria because they used them as a energy source and supply to maintain their health.

1) The Life Cycle-- tracing the development of a baby from the fetus stage to old-age adulthood.

2) The genetic "evolution" of human natural selection that gives rises to the different "races" of people, which is really variations (with the emphasis on phenotypical variations) within human kind. There is nothing beyond this, as ameobas to man type of macro-evolution is not only a philosophical story, it is also not well supported scientifically. This belief is, therefore largely assumption and less scientific.

One great example of natural selection would be turtles. Most turtles have a smooth shell all the way, without many big bumps, but some turtles in a remote location were discovered to have a hump in their shells right where the turtle's neck was. Why did this happen? This was due to natural selection.

You see, the turtles that had a hump in their shell could reach much higher to get food, so they would be more likely to survive in a famine than normal turtles. The basic concept of evolution by natural selection is survival of the fittest.

Not much. While they both accept that life is here, they are two totally different ideas on how we got here. Evolution says that all life forms gradually developed from a common ancestor over millions of years. Creation says that everything was spontaneously created as they are by the God of the Bible within six days only a few thousand years ago.
