Is acquired characteristics important to the theory of evolution?
Althealasha
Yes! The theory of Evolution shows that a species will thrive if it has favorable characteristics.
A simple way of explaining it is this: Say that when humans are still in the trees, one pregnant mother is hit by a stray photon of radiation (OK I'm dumbing it down here) and her child is mutated. The child has received the 'Sleepy Smoker Gene' (OK I'm REALLY dumbing it down here. This gene may consist of nicotine sensitivity and associated drowsiness but you get the idea).
This isn't very important at the time as nobody smokes, but fast forward to 2010. Say that the sleepy smoker gene has been inherited by every 1 in 1000 people because they are descendants of this mother primate. Now, smoking is popular and more people are likely to fall asleep while smoking. These people may eventually die off and the more favourable genes in the human race will replace them. The sleepy smoker gene will disappear into obscurity and no more people will fall asleep and die while smoking.

What theory of evolution did lamarck develop in 1809?
Jean Lamarck's theory of evolution is known as zoological philosophy or the inheritance of acquired characteristics, and stated that changes to an organisms phenotype (basically what it looks like) will cause changes to it's genotype (DNA). This has been disproved of by modern scientists, with natural selection as the main theory.
What scientist suggested that organisms slowly acquired physical characteristics?
Charles Darwin and his theory of evolution. Strictly speaking, Charles Darwin did not put forward the "theory of evolution". He publish a book called "On the Origin of Species by Means of Natural Selection OR The Preservation of Favoured Races in the Struggle for Life". The theory of evolution had been around for a long time, in fact, his grandfather, Erasmus Darwin, had proposed evolution 75 years before Charles published his book. Charles Darwin gave us the driving force for evolution - Natural Selection. There had been suggestions for evolution and evidence in fossils well before Charles Darwin. It is just that nobody could work out why until Charles.
What cell theory contradicts evolution?
No theory contradicts evolution. Evolution is the basepoint of all Biology.
What is the theme that reflects that there has been a gradual change in the characteristics of species over time?
The theory of evolution. Please see the related links.
What did Darwin's theory of evolution provide that earler theories of evolution had not?
Darwin was by no means the first person to come up with a theory of evolution. However, he was the first person provide a mechanism by which evolution could occur. He called this natural selection and is essentially the way in which individuals with characterisitcs that better suit their environment survive and ones which don't die out. Therefore, eventually the whole species will possess these advantageous characteristics and evolution will have occured.
Whose theory of evolution conflict with Darwin's theory of evolution?
Lamark's theory perhaps. Acquired characteristics clash with heredity.
Theory of Evolution by Inheritance of Acquired Characteristics?
This is the theory of Lamarck and it is long refuted.
Has Lamarck's theory of evolution been proved?
Scientists do not prove things. Lamarck's theory is long refuted as acquired characteristics and the use and disuse concepts are not explanations for evolution of populations.
What are the differences of evolution and theory of evolution?
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.
How do organisms change over time?
The evolution of a organism depends on what type of organism it is
Lemarck's ideas of evolution are known as the inheritance of acquired characteristics what was incorrect about his theory of how organisms evolve?
lemarck ideas of evolution are known as the inheritance of acquire characteristic what was incorrect about his theory of how organisms evole
Was lamarck's theory accepted or rejected?
His theory of use and disuse was rejected.
How was Lamarc's theory of evolution wrong?
He incorporated the Acquired Traits theory into evolution, which Darwin's research proved as BS.
What was wrong with lamarck's theory of evolution'?
His two main concepts, acquired characteristics and a innate " desire " to evolve, were both unsupported by any evidence and were not the way evolution happens. So, Lamarck's " theory " ( in the vulgar sense ) was utterly refuted by the actual evidence and process of evolution.
What are the differences between darwin and lamarck's theory of evolution?
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.

Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.
What question did both Lamarck and Darwin try to answer with their theories of evolution?
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
