Darwin's research showed that species can be modified for different ends, our that species adapt to their living environment to stay alive. That is why he called it "The survival of the fittest". This answers the question of who made the selection of what is to be evolved. This theory is known as Natural Selection. The species that do survive in the competition for existence will go on to produce the next generation.
Many scientists at this time did not agree with Darwin's theory.
They did not think it was a revolution. As time went on, this theory
was
more accepted, and is now considered a true revolution.
Second Contribution--Tylor Young
Charles Darwin had an instrumental part in bringing the theory of
evolution to light. His revolutionary ideas on evolution sparked
controversy and shed light on many unanswered questions that the
scientific community had about the subject during the nineteenth
century. The "Voyage of the Beagle" and "The Origin of Species" were his
most read books on the subject that he studied. His theory of
evolution was a drastic proposition for the time, but he quickly gained
numerous followers in both the scientific community and from the public.
Darwin was born on 12 February, 1809 in Shrewsbury, England. His
father, Robert Darwin was a successful doctor in Shrewsbury. Charles
had plans to be a doctor also, but his plans changed as his life took
its course. He showed an interset in many subjects at an early age.
He developed an urge to travel, had a passion for shooting, collected
minerals, insects and birds. All these traits would later come in handy
when he traveled around the world to conduct his studies.
Darwin went to Cambridge to become a clergyman. In retrospect,
Darwin concluded that his time at Cambridge was useless to him but two
good things came from his time there. Field courses and meeting a Dr.
Henslow were his good experiences at Cambridge. Dr. Henslow interested
him in geology, botany, and entomology. It was Henslow that
introduced Darwin to Captain Fitz-Roy, of the Beagle.
Darwin was on the Beagle for nearly 5 years. Back from the trip
he got married and settled down to work. His health was poor and he
attempted to compile notes of his trip around the world. His
compilation turned into the "Origin of Species" and it was published in
1859.
