    Many christians continue to ignore the clear evidence of evolution being
    used to design things in this world, preferring to believe that random
    mutation has no place in a well designed system. Well, the company I am
    using for an internet provider here is Scotland has designed their network
    by using random mutation, and sex. Duncan Grahame-Rowe writes:

            “Information sent over the Internet is broken up into discrete packets
    which are stored in a ‘buffer’ memory before being forwarded to the next leg
    of their journey. Ideally, buffers are long, but the more information the
    packets hold, the slower they move. “If a packet arrives at the buffer and
    it is full, then it tends to get thrown away,’ says Marhsall. This means
    some information will be lost.
            “What is needed is the ability for buffers to know what kind of information
    they are passing and adapt their length according to the need. To do this
    using traditional techniques will become impossible as the Internet grows.
    So BT turned to nature in the form of ‘genetic algoriths’. These are
    biologically inspired programs commonly used to help design—or evolve—things
    that people find difficult.
            Gas mimic natural selection by treating strings of data like genetic
    material. These strings can be combined and mutated to produce offspring
    whose fitness is then evaluated. The best are ‘bred’ to produce more
    offspring. This is repeated until the best design has evolved. The problem
    BT found was that Gas are too slow for real-time applications, since they
    require the evaluation to take place over many generations. So Marshall and
    his colleagues proposed a different biologically inspired solution.
            “Bacteria don’t have sex in the traditional sense, they reproduce using a
    technique known as plasmid migration. ‘They wander around and bump into each
    other and say ‘hi, do you want some of my genetic material’,” Explains Inman
    Harvey, an artificial intelligence researcher at the University of Sussex.
    By exchanging plasmids (rings of genetic information) through their cell
    membranes with neighbouring cells, successful genes can pass quickly through
    a colony and allow it to adapt rapidly to its environment. Random mutations
    produce new genes, with successful genes flourishing and ineffective ones
    quickly dying off."

    If human engineers can use evolution and random mutation to design man made
    items, which are clearly intentionally designed, why on earth do we make God
    less than us and restrict his creative acts to those of a 19th century,
    Newtonian designer? If man can use evolution as a design tool then surely
    God can also.
