==Key Stage 4==
===Meaning===
[[Jean-Baptiste Lamark]] was a [[scientist]] who first developed a 'theory of evolution' in which the behaviour and environment of an [[organism]] would cause it to change in its lifetime and those changes could be passed on to their [[offspring]].
===About Jean-Baptiste Lamark===
: In the early 19th century [[Jean-Baptiste Lamark]] developed a 'theory of evolution'. However, he did not propose [[Natural Selection|natural selection]] as the cause.
: [[Jean-Baptiste Lamark|Lamark]] believed that the behaviour and environment of an [[organism]] would cause it to change in its lifetime and those changes could be passed on to their [[offspring]].
: He suggested that the '''evolution''' of the [[giraffe]] was caused by many generations of [[giraffe]] stretching their necks to reach higher food. When a [[giraffe]] stretched its neck then the [[offspring]] would also have longer necks.
: [[Jean-Baptiste Lamark]] believed that all [[species]] began as simple worms which would spontaneously appear and over time their behaviour and environment would change them and pass that change onto their offspring.
: [[Jean-Baptiste Lamark]] was right that [[species]] 'evolve' over generations, but wrong about the cause.
