what is the theory of evolution?

Answer 1

Exactly. Wow that's deep.

Answer 2

The theory of evolution is that the mechanism for evolution or changes within a species are caused by natural selection, mutations, or other factors.

Answer 4

Hello,

If you want a very in depth and precise explanation of Darwins Theory of Evolution through the process of natural selection. His Beagal diaries from his 5year journey sailing to the Galapagos Islands,etc Can be found online here:-

http://darwin-online.org.uk/

PS:- Darwin was only something like 23years old when he explored Galapagos but it took him another 20 years before he crystalised his unique ideas on natural selection and eventualy published his great book on the Origin of Species. Which turned the world upside down at the time, remember that was only just before the end of the century too.

Answer 5

Excellent question. Most people do not understand it. It is more accurately described as a hypothesis, since any idea about the past is not subject to the scientific method of observe, repeat, test, etc.
It is really a philosophical or religious idea which seeks to interpret the evidence within a naturalistic (no God) framework, or worldview.

The word evolution has different meanings. The neo-darwinian hypothesis of evolution (goo-to-you) is the idea that all life has arisen from the simplest life form by means of Genetic mutations which are acted on by natural selection. Darwin did not know about genetics - this has been added later - hence "neo".

In fact genetics is the death knell for Darwinism, for far from providing the source of new information, mutations result only in the loss of information. Even Dawkins could not supply an example of a mutation that adds information. And information is key - you would need a mind boggling amount of information to appear to change from one kind of living thing into another.

What we actually observe (eg in darwins finches) is great variability within kinds, but stasis between kinds. We have bred many variations of dogs, but they are all...well...dogs!

Many evolutionists (deliberately) confuse natural selection with (goo-to-you) evolution, by calling natural selection evolution.

Natural selection happens. Creationists absolutely agree. There is much evidence for it, and it has been demonstrated and proved. This is completely different to the hypothesis of neo-darwiniam evolution, for which there is precious little evidence in favour and much evidence against.

Answer 6

Not the Theory of Creationism. In other words that we have had constant changes in the gene pool of populations from generation to generation by such processes as mutation, natural selection, and genetic drift.

Answer 7

It is a bit of a cheek to ask such a question as this on here and expect people to spend a lot of time summarising a huge body of work in a vast academic subject when its very easy to go online and get summaries.

If you're genuinely interested you can't do much better than Darwin's original 'Origin of Species'.

Answer 8

.... is it theoretical? is it indeed happening at all.. or is it just down to darwin, who had a good idea... then realised what he'd done...

read page one of his biography... within 5 years of the journey on the beagle he was already having doubts as to the validitiy of his work.

darwin saw the equivalent of a turner landscape thru a ballpoint pen case... he missed lots and drew the wrong conclusions... it wqas reported to teh royal society and recorded in The Times...and accepted by a hungry world... and its all rubbish..

Man does not evolve, he adapts. and there is a difference. in evolution the zygote either lives or dies..there is no middle ground. we can only develop at the conception. outside that, its all DNA, amino acids and some luck...

evolution is like a combination lock... it has millions of viable combinations..but only one will unlock the thing...

everything else is speculation and conjecture...

Answer 9

In biology, evolution is change in the heritable traits of a population over successive generations, as determined by changes in the allele frequencies of genes. Over time, this process can result in speciation, the development of new species from existing ones.

All contemporary organisms on earth are related to each other through common descent, the products of cumulative evolutionary changes over billions of years. Evolution is thus the source of the vast diversity of life on Earth, including the many extinct species attested to in the fossil record.

According to the theory of evolution, the basic mechanisms that produce evolutionary change are natural selection (which includes ecological, sexual, and kin selection) and genetic drift; these two mechanisms act on the genetic variation created by mutation, genetic recombination, and gene flow.

The theory of natural selection was first set out in a joint presentation in 1858 of a pair of papers by Charles Darwin and Alfred Russel Wallace and popularized in Darwin's 1859 book The Origin of Species. Natural selection is the process by which individual organisms with favorable traits are more likely to survive and reproduce. If those traits are heritable, they are passed to the organisms' offspring, with the result that beneficial heritable traits become more common in the next generation.Given enough time, this passive process can result in varied adaptations to changing environmental conditions.

In the 1930s, Darwinian natural selection was combined with the theory of Mendelian heredity to form the modern evolutionary synthesis, also known as "Neo-Darwinism". The modern synthesis describes evolution as a change in the frequency of alleles within a population from one generation to the next. With its enormous explanatory and predictive power, this theory has become the central organizing principle of modern biology, relating directly to topics such as the origin of antibiotic resistance in bacteria, eusociality in insects, and the biodiversity of Earth's ecosystem.

Answer 10

there are many types of theory.

Panspermia theory - suggests life evolved from another planet from cosmic dust carrying complex organic compounds.

Spontaneous origin - this theory suggests that life is simply just got more complex with cells developing into clusters etc.

Endosymbiont theory - this theroy suggests that eukaryotic cells (animal cells, like us) were created from prokaryotic cells (bacteria) by the engulfing of another prokarayotic cell. This can be seen with similar ribosomes present in mitochondria and chloroplast with that of prokarayotic cells.

Creator - that we were created by god. personaly this is what i believe is true.

Answer 11

the theory is we all are evolved from monkeys, my theory is we came from different types of monkey and if you look at peoples habits you will have to agree. some monkeys pick their noses and wipe the fingers on another passing monkey. others recognising protien eat the stuff. For ease of the language we often refer to these lumps of goo as crows or bogeys. Try a crow sandwich, it beats roast beef and I'l swap you two white ones for just one black one any day of the week..............
