Mendel's Laws explain most of the physical variations observed in living things. Genes, the genetic units of .
heredity, are merely reshuffled from one generation to another, but new genes are never formed. Different .
combinations create variations, but these variations are limited. Each cow, person, dog, etc. has variations, .
but the genetic units do not permit dog-people, or cow-dogs. Breeding experiments by competent .
biologists confirm that these boundaries exist.(Fix,1984). Since mutations are the only mechanism .
(according to Darwin) by which new genetic material becomes available, then mutations must have .
occurred regularly to have spawned all our present life forms, and further, mutation must consistently go .
from simple to complex to have gotten us out of the primordial ooze. However, many noted biologists, .
including C.P. Martin and Theodosius Dobzhansky (who mutated the fruit fly), consistently report that .
mutation does produce hereditary changes, but "invariably affec!.

brain has over a hundred thousand billion electrical connections), and further, all animals are born with .
fully developed organs. If evolution were occurring, at some point people could expect to see a reptile .
whose leg was becoming a wing, but they never have. Darwin himself attempted to answer a question put .
to him by Harvard biology professor Asa Gray, regarding the eye, and whether the "inimitable contrivances .
for adjusting the focus to different distances, and for the correct ionospherical and chromatic aberration, .
could have been formed by natural selection. This seems. absurd in the highest degree."(Darwin,1927). .
Genetic and molecular biologists can now measure the degree of similarity between most forms of life by .
What is evolution? ... Evolution also has two subunits which can be divided into micro evolution and macro evolution. The kind of evolution documented above is micro evolution. ... I think the difference between the two is senseless because macro evolution is cumulative micro evolution. ... The word evolution has many different meanings. ...
Evolution The origins of mankind is an extremely controversial issue within today's society. ... One such argument is the conflict involving the theory of evolution versus the theory of creation. After extensive scientific research, it is apparent that the theory of evolution is correct. ... Similarities in these categories link species together and are therefore studied to support evolutionism. ... Darwin proposed that evolution occurred as the result of natural selection. ...
Evolution Evolution is the change that species undergo over time. ... Evolution can be found in fossil records and chemical and structural similarities. ... Probably the most popular evidence for evolution is the numerous fossils found over time. ... Therefore, evolution will have occurred. ... The most popular piece of evidence for evolution are the fossil records. ...
Discussion Assignment # 2, Topic 2 Conflicts between scientists and nonscientist's beliefs of evolution are nothing new to the scientific community. Scientists spend years solely on the research of evolution theories to provide evidence for evolution. This enables them to present facts and defend evolution as a truth. However, showing clear-cut evidence to a nonscientist that evolution exists still presents a major problem. ... Archeological fossils have been found that creates some evidence that points to more or less evolution. ...
Today's human being is the product of millions of years of trial and error through the process of evolution. Charles Darwin was the first to bring fourth the idea of evolution. ... Evolution is the most logical explanation for mans place on earth. ... Almost all scientists believe in some sort of evolution, though they may not agree on all the details they all agree that evolution is the reason for mans place on earth. ... Even with all the proof pointing towards evolution the majority of the world still believes in spontaneous creation by God. ...
The Theory of Evolution The theory of evolution creates tremendous controversy in today's society. Anything as controversial as the creation/evolution debate is bound to generate a diversity of opinions. ... I believe the theory of evolution should be banned from educational courses because of religious conflict. ... Much evidence can be provided against the theory of evolution. ... Evolution supports the idea that humans and apes evolved from a single common ancestor. ...
Creationists say that the evolution theory is biased and incomplete. ... The process of evolution, which all living things developed from unicellular organisms, over billions of years Exactly how evolution occurs is still debated but it is a scientific fact that it does occur. ... Evolution apparently has no built-in direction or purpose. ... It is clear that evolution is much clearer to understand and accept than the creationism theory. There will always be people who will still be curious as to how we appeared on the earth, and some people will oppose the evolution theory, therefore, the evo...
