Adult belief In Evolution (Aug. 11, 2005 Scie

Scientific principles, of course, are not
reached through opinion polls. But the climate of
public opinion about evolution strongly affects
science education at the secondary level and all
political and social discourse on evolution---a
topic scientifically well accepted but
politically and socially still highly
controversial. ---Kendrick Frazier, former edi
tor of Science News and currently editor of
Skeptical Inquirer

10 Myths About Evolution
  • Humans Evolved From Monkeys. Humans and great
    apes had a common ancestor about 5-7 million
    years ago. Humans and monkeys had a common
    ancestor about 50 million years ago.
  • Its Only A Theory. In the field of science,
    theory does not mean hypothesis or guess.
    Theory means an organized set of related ideas
    supported by numerous experiments over a long
    period of time. A theory that hasnt been
    confirmed is a hypothesis.
  • If Nobody Saw It, We Cant Be Sure It Happened.
    If your house is trashed and your TV and stereo
    is missing, will you hesitate to call the police
    because nobody saw it happen? Would you want the
    judge to dismiss the case just because you only
    had forensic evidence, but no witnesses? The
    evidence for the process of evolution is
    overwhelming. In nearly 150 years, not one
    scientific investigation has demonstrated
    evidence that evolution has or does not occur.
  • Science Cant Say Anything About Origins. Maybe
    not. But once the origin happens, everything
    after that is history. And historical evidence is
    preserved in the physical record. Arno Penzias
    and Robert Wilson at the Bell Telephone
    Laboratories in New Jersey won the Nobel Prize in
    1978 for their discovery of Cosmic Microwave
    Background (CMB) radiation, evidence of the Big
    Bang nearly 12.5 billion years ago.
  • Biologists Believe In Evolution. Science is not
    based on belief. Evolution provides a model for
    scientists to understand the relationships
    between organisms on the planet. 99 of all
    scientists ascribe to its tenants. Science is
    not about belief-it is about making inferences
    based on evidence.

10 Myths About Evolution
  • There Are No Intermediate Fossil Forms.
    Archaeopteryx, the earliest known fossil bird
    (although more recent finds may be earlier) has a
    thoroughly reptilian skeleton with a bony tail,
    teeth, and four paws with jointed fingers (not
    merely horns like todays birds). And it has
    feathers. If thats not intermediate, what is?
    More recently, there is accumulating evidence
    that some dinosaurs had hair and feathers.
  • Evolution is Not Testable. Evolution is
    observable and testable. The misconception here
    is that science is limited to controlled
    experiments that are conducted in laboratories by
    people in white lab coats. Actually, much of
    science is accomplished by gathering evidence
    from the real world and inferring how things
    work. Astronomers cannot hold stars in their
    hands and geologists cannot go back in time, but
    in both cases scientists can learn a great deal
    by using multiple lines of evidence to make valid
    and useful inferences about their objects of
    study. The same is true of the study of the
    evolutionary history of life on Earth, and as a
    matter of fact, many mechanisms of evolution are
    studied through direct experimentation as in more
    familiar sciences.
  • Evolution Means Humans Are Just Animals. Well,
    what are you then? Vegetable or mineral? Humans
    have hair and nurse their young just like other
    mammals. Trails like nurturing, cooperation and
    monogamy are often favored by evolution because
    they enhance the survival of the species.
  • Evolution Is Just Random. Is the following number
    sequence random 5626535897932384626433383279? It
    not only looks random it is random. But is it
    lacking in meaning? No. These are the digits of
    pi beginning with the fourth decimal place.
    Random does not mean meaningless.
  • Complexity Cannot Arise Naturally. Since many
    complex traits seem to be adaptive, they are
    likely to have evolved in small steps through
    natural selection. That is, intermediate forms of
    the adaptation must have evolved before evolution
    arrived at a fully-fledged wing, chemical
    pathway, or eye.
