<em>Lamarck's theory of evolution</em> was based around how living beings<em> (for example animals, plants)</em> change during their lifetime, and then pass these progressions onto their offspring
The model used to explain the concept of <em>utilization and neglect is the stretched neck of the giraffe</em>
As indicated by Lamarck's hypothesis, a given giraffe could, over a lifetime of stressing to arrive at <em>high branches, build up a lengthened neck</em>
<em>The development of long neck in giraffes is an example of Lamarck's theory of evolution</em>
