Just realised I don't remember Lamarck and Eldridge/Gould from MOB in the little table you made! Haha! :D
Who are they...? :P
Thank you! :D

Hey so in the table I'd just have a one-line summary of what they did, or even just one keyword to jog my memory!
Lamarck proposed the theory of 'Inheritance of Acquired Characteristics'... Basically he believed that if a parent acquired a characteristic over the course of their life, then they'd pass it on to their children genetically (not true! it has to be a mutation in the gametes to be passed on!). The example he used for this was that he saw giraffes stretching their neck to reach leaves high up on trees. He thought that if parents stretched their necks, the baby giraffes would inherit longer necks.
Eldridge and Gould proposed the theory of 'Punctuated Equilibrium' - that evolution is not just a linear process (always occurring at the same rate), but that there are periods of fast evolution followed by not much change at all, prompted by environmental change. Makes a lot of sense if you think about it! Especially given that evolution by natural selection is driven by environmental change.

You really need to have a snickers
Sanaz:
Epigenetics now suggests otherwise, maybe Lamarck was right in a way ;)
