Is Darwin's Theory of Evolution true?
There is plenty of fossil records and observable speciation to provide evidence for Evolution. Within the scientific community there is little to no debate on whether evolution is wrong. No concrete evidence has been provided by anyone to dispute the claims of evolution since its formulation by Darwin, otherwise it would have been discarded through the scientific method.
--------------------------------------------------------------------------------------------
While the above is right, observation and scientific studies provide evidence and arguments to the theory.
No. Evolution is based on empirical, scientific data. It is in no way a merely social philosophical construct. The conjecture was founded upon hard physical evidence, and was built into a solid, robust theory, which now forms the foundation tying all the biological sciences together into one unified whole.
Evolution underpins biology the way the plate tectonics underlies geology.
What is the function of fat cell?
A fat cells primary function is to store fat, quite simply. But recent discoveries show that the fat cell also produce the hormone leptin which decreases appetite. This means that fat cells play a role in food intake as a homeostatic mechanism. Also brown fat cells, which are present in babies and antarctic sea creatures, have an interesting function. The mitochondria in them are slightly modified not to have a specific protein that makes ATP from ADP and Pi using energy from H ions moving through the membrane. Instead these H ions move t via another protein which instead of ATP produces heat directly. And thus brown fat actually produced heat, is not just an insulator.
You can alter human evolution?
I believe that yes you can alter human evolution not in the sense that you can change our very exsistence but in the sense that you could"ve postponed it. Such as the way we and other people interbreed some of the evolution of homo sapiens definitley formed that way but they were also already in exsistence and in competition with neanderthals. So yes I say you can alter it but no to that much of an extent.
The earth began to be formed over 4.5 billion years ago,but for millions of years nothing could live here.Gradually,the earth's crust and the atmosphere formed.The simplest form of life, bacteria and algae,probably began to grow less than four billion years ago.Human beings did not appear until about two million years ago.
How do the germ layers of radiata and other eumetazoa differ?
Radiata contain two germ layers including the ectoderm and the endoderm, other Eumetazoa differ in that they have an additional layer called the mesoderm.
What are the different types of adaptations?
Diferent types of diaplay adapter are:
1. CGA
2. EGA
3. PGA
4. VGA
5. HDMI
6. Display Port
7. DVI
The last four are the most used today, and HDMI is the best connection as it can support 4K video.
How does the theory of evolution explain variety within species?
The General Theory of Evolution posits that change occurs not only 'within' a species, but also 'across' species. In this way, change is actually unlimited in the sense that, given the right circumstances and given the right environmental pressures, any form of biological life could eventually be pushed from one species to another. A lizard could be pushed into the form of a bird; a whale could be pushed into the form of a wolf. So, as we take a look at the General Theory of Evolution (AKA Macroevolution)
What are the practicability of evolution?
There is no practability when you talk about evolution. Evolution is false. Let me point out why. The evolutionists say that the big bang formed the earth and all matter. They also say that the big bang happened because of a squeeze on all matter so hard that they exploded and all of the matter went flying, then became organized into our earth and all matter. Not true. First of all, it is not true that matter could be squeezed so tight it exploded. Even if that could happen, when matter explodes it gets disorganized it does not become organized.
What is the best evidence that many different geologic periods are represented in Virginia?
The presence of fossils of different ages
Who disproved the idea of inheritance of acquired traits using tailless mice?
August Weismann
but actually this theory of his was wrong.......
Lamarck's idea was more appropriate...........
What dangers might travelers face in the devonian period?
A traveler should watch out for armored placoderms. If the traveler is in the Early Devonian, these fish did not have teeth, but plates in their jaws that acted as teeth. By the late Devonian though, they had developed jaws that could measure up to 33 ft. The only thing a traveler should worry about on land is insects, because no other animals existed during this period. The traveler should watch out if they are visiting the Late Devonian because of the high levels of carbon dioxide in the atmosphere, colder temperatures, and meteorites striking the earth,
Who formulated the theory of evolution?
Jean-Baptiste Lamarck was the first person to clearly formulate and present a plausible theory of evolution. Lamarck was a French naturalist who lived from 1744 to 1829.
Any proposition can be denied by those who do not wish to accept it, no matter how strong the evidence is. However, evolution can not rationally be denied. Scientists say they regard it as fact.

How does Mendel's theory of inheritance support Darwin's theory of natural selection?
Mendel's laws deal with the transmission of genes between individuals. Evolution deals with changes in gene frequencies within and between populations.Population genetics, which mathematically analyzes how gene frequencies change over time in populations, is the backbone of evolutionary genetics, and it is based on Mendelian genetics being the transmission mechanism for individuals. So, the statement that Mendel's work "raises great obstacles" to evolutionary theory is simply ignorant and misleading.
Mendelian genetics support evolutionary theory in every way.
Actually, it doesn't. Darwin was unaware of Mendel's theory when he wrote his theory of Evolution (even though they lived at the same time), and because of the strong belief in Darwin's ideas it was not until the early 20'th century that the importance of the Mendelian theory was realized.
The Mendelian theory - because it showed that genes are own entities - raises great obstacles for the Darwinian theory. Natural selection operates on the organism level, rather than the gene level (the whole organism dies, if only one single fatal mutation occurs), which will mean that all the "good" mutations that need to add up during long time will get lost due only to a small number of fatal mutations, which makes it even more impossible for natural selection to give rise to something new which needs adding up of "good mutations".
The concept of "good mutations" - mutations that will be good only when many such mutations have been added together - is itself an erroneous way of thinking, because it builds on teleological reasoning (things get their "meaning" only after something has happened and you see the result) rather than causal reasoning ("cause gives effect"). Teleological reasoning is not rational in a naturalistic framework, because the only thing there is in such a framework is "cause gives effect".
There are alternate versions of a gene.
Natural selection is when biological organisms with favorable traits survive and reproduce more successfully than organisms that do not possess such traits. Organisms with negative or less useful traits survive and reproduce less successfully than organisms lacking such harmful traits. Natural selection played a huge part in the evolution of the great barracuda. The barracuda had to adapt their distinctive shape, design, and skills over the years and did so through many generations.
How does natural selection enable populations to grow?
The growth or shrinkage of populations has nothing to do with natural selection, but with the availability of resources, and the ability of organisms to utilize those resources. This is also known as 'carrying capacity'. The natural tendency is for organisms to produce more offspring than the environment can support. So if the environment supports more individuals, then the population will automatically grow. If conditions change and the environment supports less individuals, then some individuals will starve or be otherwise unable to reproduce. Natural selection, in this case, "determines" which individuals pass, and which do not.
Do germs have anything to do with evolution?
By "germs" I have to assume you mean bacteria. And yes, it is supposed that the first organism was a prokaryotic cell, followed by eukaryotic cells such as plants.
