Hi Vale! Did you know all about the lesson that ma’am caluna discussed yesterday? I didn’t attend class yesteray due to my sickness.
Yes, It’s my plessure to share with you the lesson and it’s all about pre-darwinian theories of change
So can you please share to me the lesson that ma’am caluna discussed?
Oh, this person is more on specific organs of related animals that have a structural variations.
Empedocles and Aristotle, Georges Louis-Buffon, Erasmus Darwin and Jean Baptiste Lamarck
Pre-darwinian theories of change is an ideas about evolutionary change.
Thank you so much! I will listen to you
Empedocles has four element theory proved to be remarkably long-lived. About a century after Empedocles devised it, Aristotle popularized and added to it.
Empedocles’ four elements came to be known as the Aristotelian Elements.
First, the philosophers Empedocles (495-435 B.C) and Aristotle (384-322 B.C) described concepts of change in living organisms over time.
Hmmmm that’s why the four elements called as the Aristotelian Elements.
He believed in a special creation of species and considered change as being degenerate.
Second, Georges-Louis Buffon (1707-1788 )
His observation of structural variations in particular organs of related animals convinced him that change must have occurred during history of life on earth.
He believed in the common ancestry of all organisms.
Third, Erasmus Darwin (1731-1802).A physician and the grandfather of Charles Darwin. He was intensely interested in questions of origin and change.
Okay I get it, Next is?
Lamarck’s acceptance of a theory of inheritance that we now know is not correct led him to erroneous conclusions about how evolution occurs.
Lastly, Jean Baptiste Lamarck (1744-1829) A distinguished French zoologist.
His contributions to zoology include important studies of animal classification and his theory was based on a widely accepted theory of inheritance that organisms develop new organs, or modify existing organs, as needs arise.
Vale, Thank you for sharing this lesson to me. It really helps me a lot.
So that’s why It called the Pre-darwinian theories of change.
