Answer 2

Answer:

Explanation:

Lamarck explained his belief that all organisms came from a rudimentary state of being which was far less complex than what we see today.

         Darwin believed in the theory of evolution through natural selection. Darwin proposed that new traits were developed through random chance, and that if these traits helped an animal by increasing its ability to reproduce, then the trait would be passed onto the offspring. 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. Because this individual had a longer neck, it was able to reach food sources that other animals couldn’t. Having access to more food allowed the giraffe to live longer and reproduce more, ultimately leading to more long-neck giraffes. Successive generations of this continued to favor individuals who were born with longer and longer necks, which eventually lead to the giraffes we know today.
