Do you know how giraffes got their high neck??


"Originally the neck of the Giraffe where not Long"
Now we are going to see about that,we have a answer for this too.Once there lived a Philosophie Zoologique named Lamarck presented an explanation for the origin of a new species.He is called as Jean Baptiste Lamarck.He lived since 1744-1829.His theory was based on his belief in two biological processes:The two biological processes are use and disuse of organs and inheritance of acquired characters.At 1st Lamarck's ideas where widely accepted.Since he could not support his theory of evolution with data and information.His thoughts where all hypnotical.
He took Giraffe as an Example,Lamarck believed that ancient giraffes had short necks and they used to feed grass only.When that grass became scarce and grow far the giraffes stretched their necks to reach leaves of trees.That stretching leads to giraffe's neck length high.This type of data and information have said by Lamarck.In this way organisms have change as environment changes.
