How would Darwin and Lamarck both explain the long neck of the giraffe?

In terms of the giraffe example, Darwin’s theory of evolution through natural selection would suggest that a giraffe was born with a longer neck by random chance. Having access to more food allowed the giraffe to live longer and reproduce more, ultimately leading to more long-neck giraffes.

How would Jean Baptiste Lamarck’s and Charles Darwin’s explanation on evolution of the tail differ from each other?

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.

How Lamarck and Darwin explained evolution?

Lamarck’s theory was called the theory of acquired characteristics and Darwin’s was called the theory of evolution by natural selection. Darwin theory said that organisms get helpful variation before changes in the environment. He thought they got the variation by chance at birth.

How did Darwin disprove Lamarck explain why Darwin still thought that Lamarck’s idea was very important?

Lamarck’s Theory of Inheritance of Acquired Characteristics has been disproved. The other way that Lamarck’s theory has been proven wrong is the study of genetics. Darwin knew that traits are passed on, but he never understood how they are passed on.

What caused giraffes to have long necks?

In short, giraffes’ long necks are the result of generation upon generation of repeated stretching and inheritance. Instead he argued that the giraffe’s neck results from repeated “natural selection”. Long-necked giraffes were more likely to survive hard times than their short-necked rivals.

Do you agree with what the theories of Lamarck and Darwin argues?

Darwin refuted Lamarck’s hypothesis that individuals change to meet needs due to environmental stress and that these acquired characteristics are passed on to offspring. Wallace and Darwin independently developed their theories and Darwin presented his findings with Wallace.

How did Darwin disprove Lamarck explain why Darwin still thought Lamarck’s idea was very important?

Which statement best describes the difference between Darwin and Lamarck?

What is the difference between Darwin’s theory of evolution and Lamarck’s theory of evolution? Lamarck believed that organisms could acquire characteristics during their lifetime that they could pass down to their offspring, but Darwin did not believe these traits could be passed down.

Why was Lamarck’s theory disproved explain?

Lamarck’s theory cannot account for all the observations made about life on Earth. For instance, his theory implies that all organisms would gradually become complex, and simple organisms disappear.
