This is called irreducible complexity.
Actually it isn't. Irreducible complexity is something else entirely. Irreducible complexity is a prediction of the theory of evolution and was made in the early 20th Century:
Muller 1918 pp. 463-464 writes:
"... thus a complicated machine was gradually built up whose
effective working was dependent upon the interlocking action of
very numerous different elementary parts or factors, and many of
the characters and factors which, when new, were originally
merely an asset finally became necessary because other necessary
characters and factors had subsequently become changed so as to
be dependent on the former. It must result, in consequence, that
a dropping out of, or even a slight change in any one of these
parts is very likely to disturb fatally the whole machinery; for
this reason we should expect very many, if not most, mutations to
result in lethal factors ..."
(emphasis in the original)
What evolved first, the animals eyes to see the prey, teeth to chew the prey, stomach to digest the prey, ect.?
The eyes.
Darwin's theory was inspired before he realized how complex cells are. It is outdated and should not be taught in school.
Agreed. We should teach the modern theory of evolution instead.
