The neo-Darwinist attachment to Natural Selection has arrested the development of science for too long.

Sciencing on MSNThings People Get Wrong About EvolutionThe Theory of Evolution has been around for over 150 years now, but there are probably some things about it that you don't ...
Evolution can be defined as the change in the frequency of a phenotype in a population over many generations. Mutations can be inherited if they occur in DNA that is passed on to the next ...
This is because, as we have seen, rare alleles are found mostly in heterozygotes, such that a new recessive mutation can’t be “seen” by natural selection until it reaches a high enough ...
With time the mutation that is benefited accumulates and a different organism is formed with an entirely different creature. According to Charles Darwin, natural selection acts to preserve and ...
Natural selection, one of the most important theories in biology, was formulated by evolutionary biologist Charles Darwin in the 19th century. The theory can be used to explain the imbalance on a ...
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes ...
Natural selection is the process by which some organisms in a population survive and reproduce, while others do not, based on their bodies and behaviour. It is one of the processes by which ...
If negative selection is too weak to remove harmful mutations, then deleterious mutation accumulation will occur, and a gradual decay of genomic integrity will be the result. This can lead to ...

Dropbox on MSNGenetic Mutation in Wild Jaguars: A Breakthrough or a Natural Fluke?Scientists have discovered a genetic mutation in wild jaguars, sparking a heated debate: should we intervene and preserve this mutation, or allow natural selection to take its course? As we face ...
How could a "bad" gene-- the mutation that causes the sometimes lethal sickle cell disease -- also be beneficial? On the other hand, if it didn't provide some survival advantage, why had the ...
