To produce offspring, males and females contribute specialized reproductive cells called gametes--sperm cells from males and eggs from females. Most genes used to manufacture gametes differ from organism to organism. Scientists were surprised, therefore, by a recent study showing that, in spite of those differences, one gene in particular was present in all the animals surveyed.

July 22, 2010, marked the 100th anniversary of genetic investigations using fruit flies.

Methodist Dallas Medical Center in 2009 averted an impending outbreak of dangerously infectious bacteria called Acinetobacter baumannii. Although less prevalent than MRSA, Acinetobacter has acquired a similar resistance to common antibiotics. Would it be accurate to refer to this change in bacteria as "evolution"?

In the late 1800s, a Darwinian concept called "transmutation of species" revolutionized historical biology. Instead of viewing animal species as the products of special creation, Darwinists believed that they resulted from a long, repetitive transformation through various "natural" or environmental pressures.

Charles Darwin proposed "natural selection" as the means by which new creatures evolve. The question then became, what does nature select? The reigning consensus is that nature selects individuals with genetic mutations, and that this eventually leads to the development of new life forms.
