Both Lamarck's theory of inheritance of acquired traits and Darwin's theory of evolution by natural selection were important because they laid the foundation for understanding how species change over time. Lamarck proposed that organisms could acquire traits during their lifetime and pass them on to their offspring, while Darwin's theory explained how species adapt to their environment through a process of natural selection. These theories revolutionized the field of Biology and continue to influence our understanding of the diversity of life on Earth.

What are the differences between Darwin's and lamarcks 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.
What scientist whose ideas about evolution were the same as Darwins?
Alfred Russel Wallace independently developed the theory of evolution by natural selection, which was very similar to Charles Darwin's ideas. Wallace and Darwin jointly published a scientific paper on the subject in 1858.
What is the status of Darwins theory today?
Darwin's theory of evolution by natural selection is widely accepted in the scientific community and forms the foundation of modern biology. It is supported by abundant evidence from various fields such as genetics, paleontology, and comparative anatomy. While some aspects of the theory have been refined and expanded upon over time, its core principles remain a fundamental part of our understanding of how life has diversified on Earth.
Who is Lamarack?
Basically he came up with an evolution theory before Darwin...According to him acquired traits could be passed on. Let's look at an example: Take a girrafe...why do they have such long necks? According to Lamarack long time ago the trees started getting taller and so the girrafes had to stretch their necks to get to the leaves. This caused an extention in their necks. And the long necks were passed on by the parents to their offsprings...u gotta remember this is Lamarack theory (NOT TRUE)!! the evolution theory we believe in today is Darwin's. AFter Lamarack Darwin started studying evolution and figured out that the long necks evolved because of a variation in species and survival of the fittest. Basically according to him, long time ago their were short-necked girrafes and long-necked girrafes but as the trees started to grow taller only the long-necked were able to survive because they could get to the leaves..
Why was Darwin voyage around the world so important?
Darwin's voyage was important because it provided him with first-hand observations of different species and environments, which led to the development of his theory of evolution by natural selection. This theory revolutionized our understanding of the origins of species and the processes driving biological diversity. Darwin's voyage laid the foundation for modern evolutionary biology.
Why are Charles Darwins' ideas so important?
He proposed a theory that attempts to explain why and the fact of evolution works.It is, so far, the best and most accurate theory that adequately explains why evolution happens.
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 scientists DID NOT influence Darwin's theory of natural selection?
Darwin read the book Lamarck wrote and said that he did not get one idea from it as it was ludicrous in content. So, Lamarck would be the one scientist that did not influence Darwin according to Darwin.
What are the differences between Darwin's and lamarcks 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.

What are the similarties between Darwin's theory of evolution and lamarck's theory of evolution?
Darwin's theory was that beneficial traits would be favored in a population by a mechanism called natural selection. Lamarck proposed that acquired traits would be passed on to the offspring. Darwin's theory is favored over Lamarck's because there is no identified mechanism for passing on acquired traits e.g., your baby will not be born with pierced ears even though yours are pierced. In Darwin's theory, the traits that are favorable for an organism offer some adaptive advantage to those members of the population that possess it. Having the advantage allows them to produce more offspring e.g., rabbits range in color from black to white--in a snowy environment, the white ones have the advantage over the darker ones so they breed, well, like rabbits.
Why is the theory of gravity so important?
The theory of gravity is important because humans need explanations to things they do not understand. The theory breaks a possibilty down to where it becomes understandable.
Why is Albert Einstein so imortant?
Einstein is 'so important' because he created the theory of relativity.
Did Lamarck believes that giraffes came to have long necks through stretching their necks?
Lamarck believed that acquired traits could be inheritable. So as each generation voluntarily extended their necks, their genetics changed, allowing them to have offspring with their necks already that length.On the other hand, Darwin would have said that the genes mutated on their own and that shorter giraffes would be unable to reach enough food and die. The rest would in turn live to pass on their beneficial genes for longer necks.
Darwin and Lamarck had different ideas about why all giraffes now have long necks why?
Lamarck would have said that the ancestors of modern-day giraffes had short necks but stretched their necks as they tried to reach leaves in trees; so, their descendants were born with longer necks. Darwin would have said that in a population of ancestral giraffes, some had slightly longer necks than others; the long-necked giraffes were better able to feed on tree leaves and as a result produced more offspring. Over time, the proportion of longnecked giraffes in the population increased.
Why were the Galapagos islands so important to Darwin's theory?
It was where he developed his theory. The Galapagos are considered the "Laboratory of Evolution." Evolution is easily observable here.
Why is Charles Darwin so important in the field of science?
He is remembered for having devised the theory of evolution, which he presented in his famous book "The Origin Of Species". This is the most important and fundamental theory in the field of biology.
