What is the difference between evolution and biological evolution?
When one refers to evolution, they are generally referring to evolutionary biology (or biological evolution). They are the same thing. Evolution (in science) is essentially the study of change in organisms (adaptation, symbiosis, microevolution, marcoevolution, etc.). Evolution, put plainly, means change. If something evolves, it means it changed. We commonly refer to "evolution" as meaning something has developed further and/or better. However this is not necessarily the case. With natural selection, traits that are randomly produced either get discarded or get favored, and that gene is passed on to the next generation (should that organism reproduce). It is a very slow process, and change happens at very small levels. An organism with a certain gene isn't going to give birth to a dramatically different looking creature. That just isn't the way it works.
How has the Scientific theory of evolution developed over the past 300 years?
Before Charles Darwin published his theory in the 1850s, there really was no scientific theory of evolution. Thus the theory is actually only a little over 150 years old. In the 1920s there was a revolution in our understanding of genetics, which was incorporated into the theory of evolution. That was known as "the modern synthesis." Since that time virtually every paper published on genetics, embryology, paleontology, or any other branch of biology has further strengthened the theory.
Is there more information for or against evolution?
On almost a monthly basis, more data comes to light in the form of new fossils and other finds, that further support the Theory of Evolution.Charles Darwin (1809-1892) was not the first to study evolution, but he developed the Theory of Evolution by Natural Selection after observing the evidence for evolution during his voyage in HMS Beagle, and followed up by decades of research. This theory says that species evolved over time in response to changes in the natural environment, and was seen by scientists as the best explanation for the facts.There is ample evidence of the transition from one species to another, demonstrating that evolution really did occur. Conversely, there is no real evidence that evolution has not occurred. Those who debate the facts of evolution are left with unsupported hypotheses, often claiming that the world is too young for evolution to have occurred, or that the Laws of Thermodynamics disprove the theory. A third viewpoint is offered by a minority of creationists, such as Willian Dembski. As a qualified scientist, he accepts the immense age of the earth and the reality of evolution, but believes that there may be natural systems that cannot be explained entirely in terms of natural causes and that exhibit features characteristic of intelligent design.For more information, please visit: http://christianity.answers.com/theology/the-story-of-creation
Why is an evolution refered as a theory?
Because while we can trace the APPARENT path of evolution yielding the species we see around us, in most instances the transition via evolution is implied, not observed. No one was around to observe when most of the evolutionary splits are believed to have occurred so no one documented them to establish as a known fact that that was how the split occurred. In fact there are quite a few instances where scientists have changed their views on which ancestor a particular species branched off from (usually based on further discoveries). Also - theories remain theories until proven via experiments. It's rather difficult to craft an experiment to test natural evolution over any human time scale, although a limited number of experiments have been conducted via forced evolution of some species with very short life cycles.
Why do living organisms eventually die?
All living organisms eventually die because cells are progressively worn down by free radicals. Free radicals, or reactive oxygen species, are produced as side products from the biochemical reactions of cell metabolism. They are unstable molecules that will react with, and thereby damage, almost anything they come into contact with, including DNA, cell membranes, and proteins. Through evolution, organisms have developed mechanims to cope with free radicals and dispel their harmful effects. However, the detrimental effects of free radicals on cells eventually overcomes these coping mechanisms as the organism ages, eventually resulting in death. You may ask why evolution hasn't taken a step further and developed a never ending mechanism to deal with the free radical problem. The answer lies in the properties of evolution itself. Selective pressures on species only acts on individuals at the reproductive stage of life. Natural selection of an individual that lives longer over an individual that doesn't live as long wouldn't take place as both are able to pass on their genes.
What is one of the earliest forms of life?
ANSWER:Cyanobacteria. It is one of the earliest forms of life on Earth, and likely the FIRST form of life on Earth. EXPLANATION:Evidence (Fossilized Stromatolites) of the Cyanobacteria (the oxygen-producing bacteria) has been found as far back as 3.5 billion years ago. The Cyanobacteria is thought to have played a pivotal role in forming Earth's Atmosphere, because of its oxygenic photosynthesis (photosynthesis with a byproduct of Oxygen). Cyanobacteria is found in almost EVERY ENVIRONMENT: from Oceans (Salt Water), to Lakes and other fresh water, to bare rock and soil. This is further evidence that it has evolved longer than any other organisms, because of its (most-likely, evolved) survivability in such a variability of environments.
Is there an evolution of Floatzel in Pokemon Diamond and Pearl?
Floatzel is the last evolution of buizel it doesnt go any further
How do you evolve a porygon z?
Sorry there is no further evolution of porygon z
What does lapras evolve into in Pokemon?
Lapras cannot evolve any further in Pokemon, nor does it have a Mega Evolution.
Which animals did Charles Darwin study to further his theory of evolution?
pigeons pigeons
What is the chemical that comes from the breakdown of proteins?
Amino acids, but they can also be broken down further thru metabolism.
How do you get roaxion in Pokemon?
You don't, because it's not an official Pokemon. It's just some fan-made evolution of Luxray, who doesn't have any further evolution.
How do phosphates pollute waterways?
Many countries require the removal of phosphates from all waste. The reason for this is that phosphates promote the growth of cyanobacteria (blue-green algae) causing eutrophication, where the level of cyanobacteria means that other organisms cannot breed. Interestingly, further studies have shown that eutrophication only occurs in cases where the organisms that feed on cyanobacteria, such as zoo-plankton, are absent. This is usually the case due to other pollutants, such as heavy metals or pesticides
What type of reaction removes the -NH2 group in an amino acid to prepare the amino acids for further metabolism?
dehydration
What is the evolved form of seeking on Pokemon pearl?
Seaking does not evolve further since it does not have an evolution of itself.
How do you evolve Gyarados in Pokemon FireRed?
Gyarados does not evolve any further, it is the final evolution of Magikarp.
Does coffee increase metabolism?
There is no evidence to show that caffeine speeds up metabolism. For information about how caffeine/coffee can hinder weight loss, see the page link, further down this page, listed under Related Questions.
