it is when a virus changes its natural host to a new host. ex. from an animal to a human.
What type of diagram do scientists use to show how species are related?
Wherever they're found, all living things are related because they all share a common ancestor. To show how species are related, scientists create diagrams called cladograms. Like a family tree, a cladogram shows close and distant relatives. Scientists call the family tree for all species on Earth the "Tree of Life."
What is the mechanism of evolution?
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
What effect might antibacterial soaps have on the evolution of bacteria?
Provide a selective environment where those with resistance survive and replicate and those without die off. Gives rise to resistant bacteria.
What are the 16 different organisms that represent the evolution from cell to human?
the 16 different organisms that represent the evolution from cell to human are EUKARYOTE, PROTO-CHORDATE, CHORDATE, CRANIATE, JAWLESS VERTEBRATES, JAWED FISH, LOBETIN , LEOBETIN TETRAPOD,TETRAPOD, AMNIOTE, SYNAPSIDE,MAMMAL,PRIMATE, GREAT APE, HOMINID, and last HUMAN.
What did lamarck think evolution involved that caused his idea to be incorrect?
Lamarck's folly was that he thought evolution was caused by acquired traits being passed down from parent to offspring. An acquired trait is one which an organism acquires during its lifetime. This theory would suggest that a bodybuilder, who has bulked up during the course of his or her life, could pass a super-muscular physique on to the next generation. Of course we know this is not the case. The only way the bodybuilder's child is going to have a super-muscular physique is if the child also becomes a bodybuilder. The bodybuilder's child could even sit around all day eating Cheetos and playing Video Games, resulting in a very different physique from his or her parents.
Darwin's theory of evolution, the correct one, tells us that evolution is caused by inherited traits passed from parent to offspring. If a parent is naturally more muscular than average, this is a trait resulting from his or her genetics, and its possible that the child will inherit this genetic makeup and also be more muscular than average.
What is the Evolution of project management?
One evolution is from simple project management methodologies for people and organizations just looking to get a handle on a to do list. then on through a fully mature project management methodology and a project management software system.
True or false The theory of evolution is more certain than the law of gravity?
False ... but only by a little.
It's no longer the "Law" of gravity. Particles were found that do not obey the law, thus they must refer to it as a "theory" until they can revise the law. So, if we want to split hairs, in scientific terms, they are of equal validity. But those who believe in intelligent design can argue otherwise. So can the members of the flat Earth society ... with better logic.

Natural selection (survival of the fittest) means that valuable adaptations and mutations have the greatest number of surviving descendants.
What are three examples of environmental changes involved in evolution?
Three changes are probably global temperature change(Ice Age,NOW), and...nothing else. This is most likely the only environmental change that affects evolution.
Jean-baptiste lamarck proposed that organisms have what?
he proposed the organisms pass on "acquired characteristics" such as playing the piano.
How has evolution aided organisms in meeting their need for energy?
Some of the adaptations they develop through Evolution help them acquire energy.
What are 4 substances Stanley Miller put in his apparatus for his 'primordial soup' experiment?
hydrocyanic acid, formic acid, acetic acid, lactic acid
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Why do you talk about evolution as a theory not a fact?
In common usage, "theories" are problematic. If I say that "in theory" something is so, you immediately know that I'm not all that sure. There is question.
Scientists use the word in an entirely different context. A scientific theory is an attempt to describe, as accurately as possible, a body of fact that exists independently of the theory. Keep this firmly in mind: good theories explain reality; poor theories bend reality to fit the theory.
Because, Evolution is not a "fact" it is technically just a theory. A theory, in the scientific community, is much more than the generalized term it has become in every day conversation. While evolution is extremely well supported it isn't necessarily treated as a fact because it cannot be implicitly proven despite the great evidence in it's favor. Furthermore, to explain just how much weight a theory holds I'll list some examples which are common to most people Gravity, is technically just a theory even if you experience it all your life. Germ theory (the idea that pathogens and microbes cause illness in individuals), is technically just a theory even though germs causing disease have been isolated and proven to cause disease in other organisms. Cell theory, which states that all living organisms are made of cells, is technically just a theory even though you can observe these cells under a microscope. The reason that these very well established 'facts' (to use it in a liberal fashion) are called 'theories' in science is because scientific 'theory' has a different meaning from a 'theory' in everyday life, which is more accurately called a hypothesis or a conjecture. A scientific theory is a hypothesis that has held under the pressure of testing by countless scientists with different methods and can explain a natural phenomenon exceedingly well. It is as close to a 'fact' as it gets in the scientific community.
Who developed the theory of communism?
Communism is a form of socialism developed by Karl Marx, who wrote the Communist Manifesto.
How do scientist with different points of view assemble the evolutionary story of humans?
The books I have generally list the differing interpretations, and, of course, all the points on which there is general agreement.
When you're doing science, it is very important to list all the various interpretations of the evidence, and why you think some interpretations should be preferred over others.
What species most resembles humans?
This is really an opinion-based question, and is likely to get a lot of different answers. If you mean appearance-wise, I would say either a chimpanzee or bonobo. Behaviorally, I would say a virus.
it is charactirestically free flowing powers cosisiting of synthetic polimer which are biodedegradable in nature and ideally having a particle size less than 200 micro mtr.
What is the essence of Darwin's theory of evolution?
Darwin's theory outlined natural selection, as one theory within the whole of evolution: those organisms that are better able to survive long enough to reproduce more often, will pass on the genes that result in their offspring surviving longer and reproducing more as well, resulting in that set of genes becoming more common in the population as time passes.
