Answer 2

Lamarck was struck by the similarities of many of the animals he studied, and was impressed too by the burgeoning fossil record. It led him to argue that life was not fixed. When environments changed, organisms had to change their behavior to survive. If they began to use an organ more than they had in the past, it would increase in its lifetime. If a giraffe stretched its neck for leaves, for example, a "nervous fluid" would flow into its neck and make it longer. Its offspring would inherit the longer neck, and continued stretching would make it longer still over several generations. Meanwhile organs that organisms stopped using would shrink.

Answer 3

and this is called change due to use and disuse..!!

Answer 4

hope you got it..!!

It is just the adaptation made by giraffes in order to fulfill their hunger by eating the leaves of taller plants which made their necks to grow lengthier..!!
