Why did scientists reject Lamark's idea of evolution?
Lamarck led the way for and had ideas that helped Darwin. However, his observations regarding the mechanisms of evolution were, with the exception of one, totally backwards. To summarize Lamarck, he hypothesized that organisms somehow had a choice in their traits and could change to fit the environment (he called these ideas his theories of need and his theory of use and disuse). The part he was correct on was that should an organism change, they would pass the traits on to their offspring. Darwin said, basically, the opposite. Darwin observed that organisms were born with slight differences (variations) and those variations might give some members of a species an advantage in the struggle to survive in the environment. The reward for survival was that the organism got to reproduce and pass those traits on to their offspring. Of course, the offspring might show some variation and the whole process would continue to repeat. However, the bottom line with Darwin (and contrary to Lamarck) was that an organism had no choice in its traits as an organism is born with or without the advantage. Darwin, without knowing its mechanisms, recognized that genetics played a part in evolution. Darwin died not knowing of Mendel's work on genetics which, of course, substantiates Darwin's theory.
Why are Darwin's therories of evolution so controversial?
Among scientists they are not. Among those with special adgendas they are.
What did charles darwin help to explain?
Charles Darwin explained the changes in man and animals over time. Those who believe in the theory of evolution believe that living things adapt to their environment and change over time.
What did Darwin observe?
British Naturalist Charles Darwin visited Galapagos Islands in 1835. During his visit he observed that difference species were in a constant battle of survival with each other, and there was a variation in between tortoise on the sand and those in the water.
Charles Darwin observed the resemblance between organisms on the Galápagos Islands and those on the nearest coast He hypothesized that the island organisms had evolved from the coastal organisms Wha?
Charles Darwin was the first evolutionary biologist who championed the theory of natural selection.
What difficulties do you think might arise when trying to understand ideas from the past especially when those ideas are so different from our modern thinking?
When trying to understand ideas from the past that differ from our modern thinking, difficulties can arise due to cultural and historical context, language barriers, and evolving social norms. It is important to approach these ideas with an open mind and willingness to learn about the context in which they originated, rather than judging them based on present-day standards. Cross-referencing multiple sources and consulting experts can also help provide a more comprehensive understanding.

How did the study of organisms on islands help support Darwin's ideas?
It Gave evidence and the fossil organisms on the bottom or older layers were more primitive than those in upper or newer layers.
How might those pressures have influenced Columbus's treatment of the taino?
they pressuered him so he wanted to get anger and stress out so he took it out on the Taino people.
What resulted from Darwin's theory?
Darwin created a new branch of biology called evolutionary biology. His ideas angered those that believe in religion and not science. Some states in the United States banned the teaching of evolution. There was a famous Scopes Monkey Trial where John Scopes was accused of teaching evolution and he was defended by the famous William Jennings Byran.Some people took Darwin's ideas and used them to create social Darwinism. People, groups, and peoples were also subject to the "survival of the fittest." This concept has been rejected by most now.
How did Lamarck's ideas differ from Darwin's?
Lamarck believed an individual organism acquired traits during its lifetime and passed those traits on to its offspring. He lacked support for his ideas. Darwin documented how inherited traits could be passed on by natural selection, that adaptations that give an organism an advantage is passed on through subsequent generations and becomes more common. He had evidence for his ideas (finches, tortoises…).
Why did Charles Darwin advocate the argument of a designer god?
Because Darwin was young and naïve in those days. His opinions changed later in life.
How did Charles Darwin relate his work to Thomas Malthus?
According to Malthus, when food production is more than is needed by the population, the population increases; if population grows too much faster than food production, the population growth is slowed by famine, disease, and war.
What was Patrick Matthews theory of evolution?
It was exactly what he named it (Matthew 1831) in 'On Naval Timber and Arboriculture' 28 years before Darwin (1859) replicated it in the Origin of Species, namely The 'natural process of selection'.Both Darwin and Wallace fully admitted that Matthew discovered the concept. Thereafter, Darwin started mythmongering about Matthew's ideas being in an obscure book and solely in its appendix, and claiming no naturalist had read it. Darwin claimed no prior knowledge of Matthew's ideas (Wallace kept silent on that one) and Darwinists credulously swallowed those myths hook line and sinker. They simply took Darwin's word for it. So much for nullius in verba!Few people have read Matthew's book. But if you read it -- as Darwin obviously did pre-Origin, you'll see for yourself that we are celebrating a counterfeit genius on the back of the £10 note! Dr Mike Sutton (Dysologist).
What characteristic of most state constitutions created during the American revolution strongly influenced the ideas behind he American government?
Most state constitutions had rules to protect the rights of citizens or those accused of crimes.
What major events before the 20th century influenced the computer?
The typewriter, the telephone. Those are influenced the computer.
What american's writings were most influenced by enlightenment ideas?
American writings that were heavily influenced by Enlightenment ideas include those of Thomas Paine, whose works such as "Common Sense" and "The Age of Reason" championed freedom, reason, and democracy. Other key figures include Benjamin Franklin, who promoted scientific inquiry and civic engagement, and Thomas Jefferson, known for drafting the Declaration of Independence with its emphasis on natural rights and equality.
