The theory of natural selection
was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.
What theory did Charles Darwin Research lead to?
Charles Darwin’s
theory of evolution by natural selection
is the foundation upon which modern evolutionary theory is built. The theory was outlined in Darwin’s seminal work On the Origin of Species, published in 1859.
What did Darwin actually discover?
Darwin’s greatest contribution to science is that he completed the Copernican Revolution by drawing out for biology the notion of nature as a system of matter in motion governed by natural laws. With Darwin’s discovery
of natural selection
, the origin and adaptations of organisms were brought into the realm of science.
How did Charles Darwin collect research?
On his travels Darwin
collected plants, animals and fossils
, and took copious field notes. These collections and records provided the evidence he needed to develop his remarkable theory. The shells in this specimen drawer were collected by Charles Darwin during the voyage of the HMS Beagle.
What was the difference between Darwin and Lamarck?
Darwin noticed that within any population of organisms, there were always individuals with different traits. … Unlike Lamarck, who said that traits could develop and change during an animal’s lifetime, Darwin
believed that individuals were simply born with different traits
and that these differences were mostly random.
What animal did Darwin study?
Darwin studied
bees and ants
in his own garden. One of the reasons he may have held back from revealing his ideas about evolution was the problem of cooperation in social insects.
Did Darwin use the scientific method?
Despite occasional claims by Darwin himself that he proceeded according to Baconian principles or that he accumulated wholesale facts without any preconceived idea as to what they might imply, Darwin was an excellent practitioner of
the hypothetico–deductive method of science
.
Did Darwin say survival of the fittest?
Charles Darwin not only did not coin the phrase “survival of the fittest” (the phrase was invented by Herbert Spencer), but he argued against it. …
could be increased through natural selection
, that is, by the survival of the fittest.”
How did Darwin prove evolution?
Darwin proposed that evolution could be explained
by the differential survival of organisms following their naturally occurring variation
—a process he termed “natural selection.” According to this view, the offspring of organisms differ from one another and from their parents in ways that are heritable—that is, they …

Where did Darwin do his research?
He explored regions in
Brazil, Argentina, Chile, and remote islands such as the Galápagos
. He packed all of his specimens into crates and sent them back to England aboard other vessels. Upon his return to England in 1836, Darwin’s work continued.
What was Lamarck’s theory of evolution?
Lamarckism, a theory of evolution based
on the principle that physical changes in organisms during their lifetime
—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
Did Darwin agree with Lamarck?
Darwin thought that environmental effects that altered characteristics would alter gemmules, which would then be transferred to offspring. His pangenesis theory allowed for the Lamarckian idea of transmission of
acquired characteristics
through use and disuse.
Lamarck and Darwin shared the idea that
changes in physical characteristics could be inherited and were driven by environmental changes over time
. These behaviors are homologous because they are the same within two species and come from a common ancestor.
Why was Darwin’s theory accepted over Lamarck’s?
Darwin’s theory became accepted because
it had more evidence that supported it
. Lamarck’s theory suggest that all organisms become more complicated over time, and therefore doesn’t account for simple organisms, such as single-cell organisms.
Did Darwin study cats?
The first ‘Exhibition of Cats’ was a runaway success with more visitors than could be accommodated. … Darwin’s information on cats came
mostly from one of his cousins
, William Darwin Fox, whose family over the years kept ‘dozens of white cats’.
