How Old Is Humanity

New evidences suggest that the human race is very young. The journai Science reported that the age of the human race is roughiy 1,000 to 10,000 generations. Other information about mitochondriai DNA mutation rates gives an even younger age than 1,000 generations. 

Mitochondrial DNA mutation rates in the control region were measured directly by comparing mitochondrial DNA from siblings and from parents and their offspring. Mitochondrial DNA was found to mutate about 20 times faster than previously thought, at an approximate rate of one mutation (substitution) every 33 generations. 

The control region studied has about 610 base pairs. Humans typically differ from one another there by about 18 mutations. By simple mathematics, it follows that the human race is about 300 generations old. If one assumes a typical generation of about 20 years, this gives an age of about 6,000 years. 

The theory of evolution postulates that small, inaemental, beneficial steps propel the evolutionary process forward. It is much like a device where one component of that device is modified at a time, so as to improve the efficiency of the device in some way, while at the same time allowing the device to remain functioning without any other modifications. Once the device has settled into the fact that it now has an improved component, it then sees the benefit of upgrading another one. The point is that it takes these steps one at a time, sees how good that step is, and then takes another step. The device must both continue to function and improve its functionality. 

But what if the upgrade requires more than one improvement at a time Evolutionary theory cannot accommodate this. The improvement must be one step at a time, and if a component doesn t offer an advantage to an organism (i.e., it doesn t function), it win be lost or discarded. Are there devices occurring in nature that therefore cannot be explained by evolution Indeed there are many, but it only takes one to disprove the theory.
