According to Darwinism, all life on earth arose by natural variation and selection of the most fit.
Studies of outward appearances of organisms led Darwin and his successors to propose elaborate phylogenetic trees in which man was placed on a branch common to apes and monkeys.Major limbs in the animal trunk contained the fish, giving rise to reptiles, birds, and mammals.Take away any of these components and life doesn't exist.All this complexity is required at the same time and place for the most simple single-celled life.Life and its requisite requirement for replication needs it all. Furthermore, decades of experiments have failed to demonstrate an origin of any life from organic molecules, much less evolution of protein synthesis or DNA replication.
Not only is irreducible complexity required for the start of life, but each complex system in our bodies: the eye, the kidney, blood coagulation, red blood cells . Also, decades of genetic manipulation of bacteria and other organisms have never produced a new species like Darwinism would require.
Most of the emphasis has been on how similar genes are in man and bacteria, with little attention to the differences.
Where did this unique genetic information come from?
Many proteins and RNA's were similar from one life form to another, even between bacteria and man.
However, these data support intelligent design by a single set of principles just as well.
By comparison of a new gene to all others in the database using the BLAST program ( scientists can determine how similar one gene is to another. Examining all the organisms in table 1 shows a surprisingly high percentage of genes with no match in other organisms. That's 29% unique genetic information with no known origin, no possible descent.
