One of the most influential philosophers that contribute to Charles
Darwin’s theory was from Charles Lyell. Lyell’s theory of geology came
from the idea of uniformitarianism. Best defined as the assumption that
the same natural processes that function in the universe now, have
always operated in the universe in the past and apply everywhere in the
universe. Lyell would conclude that Earth was made of many gradual slow
changes made into what we know today. Similar to Darwin, Lyell had a
thoughtful effect on our understanding of life's history. Lyell
influenced Darwin so intensely that Darwin viewed evolution as a sort of
biological uniformitarianism. Evolution took place from one generation
to the next, he argued, but it worked too slowly for us to perceive.

How does Evolution work?
n
order for traits to evolve and change, they MUST be heritable. This is
one of the points that I definitely find to be of Lyell’s understanding.
Darwin could not seem to find an understanding to how traits were
passed on. But from Lyell’s beliefs, he finds that over a long course of
time things change. Just like theis traits have been passed down and
eventually changing over a long course of time, producing generation
after generation.
If the environment changes, the traits that are
helpful or adaptive to that environment will be different. As Lyell in
his theories, mentions that He found evidence for many rises and falls
of sea level, volcanoes construct on top of much older rocks. Natural
processes such as earthquakes and eruptions, which had been witnessed by
humans, were enough to produce mountain ranges. Now only were valleys
the work from huge floods but they slowly were the grinding from a
intense force of wind and water. As the environments were changing by
natural processes, traits that were adaptive lived in the surroundings.
Lyell was a huge believer in environments naturally changing and how the
world will slowly change, only those who could adapt would survive.
Darwin must of found Lyell’s beliefs in this topic something he could
grow from.
Darwin and Natural Selection: I do not find Charles
Darwin’s theory on natural selection to be that connected with the work
from Charles Lyell. Don’t get me wrong, I do think Charles Darwin would
not have gotten this far in his work without knowing what Lyell did
first, but I think Darwin’s thoughts on natural selection were stemmed
from his thoughts on evolution in geology that came first. From the
evolution of geology which Lyell thought took so long overtime, Darwin
interpreted that to the idea of people evolving over time.
The church
found that religion and science could never meet hand in hand. The book
shaped a variety of religious responses at a time of altering ideas at
this time. Developments in geology meant that there was little hostility
based on a literal reading of Genesis, but defense of the argument from
design and natural theology was central to debates over the book in the
English speaking world. The church of English interpreted the idea of
Natural Selection to be an instrument of God's design. Even though the
book had hardly implied to human evolution, it rapidly became vital to
the debate as psychological and moral qualities were seen as spiritual
aspects of the irrelevant soul, and it was believed that animals did not
have spiritual traits. This divergence could be submissive by supposing
there was some supernatural intervention on the path leading to humans,
or interpreting evolution as a decisive and progressive rise to
mankind's position at the head of nature.
Good work on Lyell's contribution. You are correct that, in terms of biology, there is little connection between Darwin's work and Lyell's. What Lyell gave to Darwin was literally TIME. By showing that the earth was millions (actually billions) of years old, not 6000 which the church argued, Lyell gave Darwin enough time for the slow processes of natural selection to work. Without that time, Darwin's theory wouldn't have worked.
ReplyDeleteYou discuss the influence of the church after the work was published, but what about before? What prevent Darwin from publishing for more than 20 years?
