Species are immutable. One does not become another, or unite with
another to produce a third. Dogs do not become cats, nor interbreed to
produce another species. A few species, so nearly related that we can
scarcely tell whether they are species or varieties, as the jackass
and the mare, may have offspring, but the offspring are sterile. The
zebra and the mare may produce a zebulon, which is likewise
sterile. And so with the offspring of other groups intermediate
between species and varieties. A human being and ape can not beget an
ape-human, showing that they are not even nearly related species.

If evolution be true, we would expect a frequent interbreeding and
interchanging of species. Even Darwin admitted that species are
immutable. God declared it in his word, and stamps it indelibly on
every species. "And God said, 'Let the earth bring forth the living
creature after its kind, cattle, and creeping thing, and beast of the
earth, after its kind'."-Gen. 1:24. How did Moses know this great
truth, unless he was told by inspiration of God?

Even plant-hybrids are not permanent. Darwin himself says: "But plants
not propagated by seed, are of little importance to us, for their
endurance is only temporary."

Even if it could be proven that species, like varieties, are formed by
development, it does not follow that genera and families and classes
are so developed. But it has not been proved that a single species has
been added by development, much less orders, families and
genera. Evolution must account for every division and sub-division to
plant and animal life. Darwin answers the objection to the sterility
of hybrids by saying, "We do not know." "But why," he says, "in the
case of distinct species, the sexual elements should so generally have
