Question
Briefly discuss the ideas of Lamarck and Darwin regarding the evolution of long necked giraffes.
Answer
Lamarck proposed that the long necks of giraffes were acquired by stretching their necks to reach leaves on high trees, and this acquired trait was passed down to their offspring. However, Darwin proposed that giraffes with longer necks had a survival advantage in their struggle for existence, allowing them to reach food sources that were higher up and out of reach of other herbivores. As a result, these individuals had a better chance of survival and reproducing, passing down their advantageous trait of long necks to their offspring. This idea is known as natural selection.
