Evolution is the change in a gene pool of a population over time. It is the theory that groups of organisms change with passage of time, mainly as a result of natural selection, so that descendants differ from their ancestors. In order for this theory to hold true, some things must be observed. F...

Few scientists have been as influential or as controversial as Charles Darwin has. He is considered by many to be the father of the theory of evolution.

How did life on earth begin? Was it simply a matter of chance or does order predispose an intelligent planner? Is man a mechanism of a higher order? What explanation does scientific information support? Attempts to answer these and other related questions have proposed many theories and beliefs....

In suggesting the process of natural selection as the means resulting in evolution, Charles Darwin shows how evolutionary changes have occurred in organisms. Genetic change through time Understanding natural selection is paramount to our comprehension of evolution. is a much more accepted than the t...

Interest is growing in the application of evolutionary and genetic behavioral ecological theory to problems of human lifetimes age specific fertility and mortality, population growth, and emerging population-environment interactions. An understanding of human evolution, particularly the effects of e...

A clone is an organism, or group of organisms derived from another organism by an asexual (nonsexual) reproductive process. A group of cells stemming from a single cell is also called a clone. Usually the members of a clone are identical in their inherited characteristics. An example of clone is ide...

Ethical Concerns of Classical Breeding and Genetic Engineering " You can stop the splitting of an atom; you can stop visiting the moon; you can stop using aerosols; you may even decide not to kill an entire population by the use of a few bombs, but you cannot recall a new form of life.&q...

Biotechnology: Pros and Cons Throughout this past semester many important ecological dilemmas have come to my attention. The most striking environmental issue that I have noted this semester has been agricultural Biotechnology. A reputable definition of Biotechnology would be "the me...

In The Origin of Species, Charles Darwin poetically entailed, "There is grandeur in this view of life . . .." Personifying Nature as the ultimate breeder, Darwin infers and hypothesizes what is arguably the most fundamental and profound scientific manifesto that governs what we now know abou...
