Question

As a scientist, you have been studying giraffes and the ways they have evolved. In preparation to speak at a conference, you will be focusing on their physical changes over time, and you would like to include information about their height and build. What role did natural selection play in the evolution of giraffe necks?

Answer 1

Answer:

As time progressed, to reach the tops of trees to eat their leaves, the giraffe's necks grew longer. Those without long necks could not reach the leaves and began to die off. This allowed only giraffes with long necks to survive. Eventually, their necks grew to the length they are now.

Hope this helps!

Answer 2

Answer:

The accepted theory of giraffe evolution is that the longest-neck giraffes have been passed on to their genes by natural selection and the animal that we see now takes millions of years.
