of the birds like swan and duck have become useful for
swimming due to living in water and snakes have lost their
legs by modifications in their body for burrowing habit

Lamarckism
1.11 Giraffe
Development of organs due to specific activities or their
degeneration due to no use at all was widely accepted but
transfer of those characters from generation to generation
was rejected. Because it had been verified many times
that modifications brought in us are not transferred to next
generation and thereby Lamarck's theory was disproved.
The living organism can transfer the characters which it
has acquired, to the next generation. This is called ancestry of
acquired characters
