Question

Giraffes were the subject of debate in the early days of evolutionary theory. LaMarck believed in acquired characteristics, while Darwin believed in evolution by natural selection. Which is an accurate match between the author, and how he would explain the long neck of giraffes

Answer 1

is it

A)
LaMarck believed that giraffes were created with long necks and remained unchanged from their original design.
B)
Darwin believed that giraffes could stretch their necks to reach leaves and then pass this trait on to their offspring.
C)
LaMarck believed that over time, shorter giraffes were starved out and giraffes with longer necks survived to reproduce.
D)
Darwin believed that giraffes with longer necks had a higher survival rate, due to ease of feeding and reproduction, and this is the way giraffes evolved.

Answer 2

Giraffes and many of their relatives fight by essentially beating each other with their necks and heads, in a process known as necking. Male giraffes use their necks like deadly weapons, whipping their necks around and clubbing their opponents with their heavy skulls. The longer and thicker the neck, the more of a punch it packs, so it seems that giraffes have long necks so that they can fight more effectively.

The neck of the giraffe has apparently evolved out of a desire to win battles, and centuries of natural selection for longer, thicker necks has led to the modern giraffe.
