When Charles Darwin published The Origin of Species 150 years
ago, he deliberately avoided the subject of the origin of life. This,
coupled with the mention of the 'Creator' in the last paragraph of the
book, led us to believe he was not willing to commit on the matter. An
international team, led by Juli Peretó of the Cavanilles Institute in
Valencia, now refutes that idea and shows that the British naturalist
did explain in other documents how our first ancestors could have come
All organic beings that have lived on Earth could be descended from
some primordial form," explained Darwin in The Origin of Species
in 1859. Despite this statement, the scientist took it upon himself to
understand the evolutional processes underlying biodiversity.
"Darwin was convinced of the incredible importance of this issue for
his theory and he had an amazingly modern materialist and evolutional
vision about the transition of inanimate chemical matter into living
matter, despite being very aware of Pasteur's experiments in opposition
to spontaneous generation," Juli Peretó, principal author of this study
and researcher at the Cavanilles Institute of Evolutional Biology and
Biodiversity at the University of Valencia, said.
The study, which is published in the latest issue of the journal Origins
of Life and Evolution of Biospheres, demonstrates that Darwin had
an advanced idea on the origin of the first species, and was troubled by
the problem. "It is utterly wrong to think that he was invoking a
divine intervention; it is also well documented that the mention of the
'Creator' in The Origin of the Species was an addition for appearance's
sake that he later regretted," affirms Peretó.
According to the researchers, all Darwin's opinions on the origin of
life can be found in his private correspondence and in his notebooks.
The exception is a review of a book on foraminiferous microorganisms
published in 1863 in the London social club Athenaeum, where Darwin
"lets his opinion on the spontaneous generation be known".
The international team, comprising Spanish, US and Mexican
scientists, has not only examined in detail the phrases, texts and
paragraphs of the letters, but has also put into context all Darwin's
opinions on the origins of life, available online and in the original
The origin of life hypothesis
A comment in a notebook dating back to 1837, in which Darwin explains
that "the intimate relationship between the vital phenomena with
chemistry and its laws makes the idea of spontaneous generation
conceivable," gave the researchers their clue.
In another famous letter sent in 1871 to his friend, the English
botanist and explorer Joseph D. Hooker, Charles Darwin imagines a small,
warm pool where the inanimate matter would arrange itself into
evolutionary matter, aided by chemical components and sufficient sources
In other letters, the naturalist admitted to colleagues such as
Alfred Russel Wallace or Ernst Haeckel that spontaneous generation was
important to the coherence of the theory. However, "at the same time, he
acknowledged that science was not advanced enough to deal with the
question (hence his reluctance to speak of it in public) and that he
would not live to see it resolved," Peretó points out.
