Missing link in man's evolution

In 1805, Jean-Baptiste Lamarck
and Gottfried Treviranus
coined the word “biology”.
... Lamarck is known for being
the first person to suggest
that humans might have arisen from apes, which he
mentioned in 1809. Charles
Darwin, the most famous
evolutionist, had a different
view. Instead of suggesting
that humans developed from apes he supported the view of
Thomas Henry Huxley that
humans and apes have a
common ancestry, each arising
into an own line of evolution.
In 1831, when he boarded HMS Beagle for the south Atlantic,
Darwin was a trainee pastor
and a firm believer in the
biblical account of the
Creation. He sailed with the
Beagle for five years as geologist and after visits to
the Galapagos Islands west of
Ecuador he developed his
theory of natural selection in
1838, sharing his observation
with only close friends while continuing his research. In the
mid-1840s Alfred Russel
Wallace had readings of two
crucial works: Charles Lyell’s
Principles of Geology and
Robert Chambers’s Vestiges of the Natural History of
Creation, early popular
examinations of biological
evolution.
