Convergent Evolution or Intelligent Design? 1

When the same complex capability is found in unrelated organisms but
not in their alleged evolutionary ancestors, evolutionists say that a
common need caused identical complexities to evolve.   They call this
convergent evolution.

For example, wings and flight occur in some birds, insects, and
mammals (bats). Pterosaurs, an extinct reptile, also had wings and
could fly. These capabilities have not been found in any of their
alleged common ancestors. Other examples of convergent evolution are
the three tiny bones in the ears of mammals: the stapes, incus, and
malleus. Their complex arrangement and precise fit give mammals the
unique ability to hear a wide range of sounds. Evolutionists say that
those bones evolved from bones in a reptile’s jaw. If so, the process
must have occurred at least twice (a)—but left no known transitional
fossils. How did the transitional organisms between reptiles and
mammals hear during those millions of years (b)? Without the ability
to hear, survival—and reptile-to-mammal evolution—would cease.

Concluding that a miracle—or any extremely unlikely event—happened
once requires strong evidence or faith; claiming that a similar
“miracle” happened repeatedly requires either incredible blind faith
or a cause common to each event, such as a common designer.

a.	“... the definitive mammalian middle ear evolved independently in
living monotremes and therians (marsupials and placentals).”  Thomas
H. Rich et al., “Independent Origins of Middle Ear Bones in Monotremes
and Therians,” Science, Vol. 307, 11 February 2005, p. 910.

“Because of the complexity of the bone arrangement, some scientists
have argued that the innovation arose just once—in a common ancestor
of the three mammalian groups. Now, analyses of a jawbone from a
specimen of Teinolophos trusleri, a shrew-size creature that lived in
Australia about 115 million years ago, have dealt a blow to that
notion.” Sid  Perkins, “Groovy Bones,” Science News, Vol. 167, 12
February 2005, p. 100.

b.	Also, for mammals to hear also requires the organ of Corti and
complex “wiring” in the brain. No known reptile (the supposed ancestor
of mammals), living or fossil, has anything resembling this amazing
organ.
