@simonpaynton – cooperative breeding is also evolving 🙂

A big difference between Lamarckianism and Darwinianism is that Lamarck’s Theory focuses on agency of individual organisms, whereas Darwinianism focused on developed biological adaptations of whole species.

Another shortcoming of Lamarack is that a giraffe with a longer neck would have to grow added hide and hair, added muscle, added…[Read more]

If survival of the fittest is the popular 1…[Read more]

The article concerning Lamarck makes sense. Darwin and Lamarck are kissing cousins. I suspect some of the most shocking adaptations are a result of the latter.

If environmental conditions interact with the RNA and DNA to produce adaptations (as was the case with C. elegans worm,) then this is actually Mendelian Genetics, not Lamarckianism.…[Read more]

Cheers Reg!

Here is one of the oldest organisms on earth that i recently ‘discovered’ and its origins and evolution would make good reading.

I recalled Pat Condell today when I was watching the first video.
