Lamarck

I was reading about Lamarck in the Wikipedia and came across this:

That year, he also published Recherches sur l'Organisation des Corps Vivants, in which he drew out his theory on evolution. He believed that all life was organized in a vertical chain, with gradation between the lowest forms and the highest forms of life, thus demonstrating a path to progressive developments in nature.

I am grateful, Alhamdulillaah, Allaah has made us of the highest form as Allaah mentioned in the surah At-Tin (95:4), translated as "We have certainly created man in the best of stature"

But not without advice (95:5-6) :

Then We return him to the lowest of the low,
Except for those who believe and do righteous deeds, for they will have a reward uninterrupted.
