Hominins: Sahelanthropus tchadensis
We begin our exploration into hominin history with an introduction to what is arguably the oldest hominin fossil yet found. Does Sahelanthropus tchadensis represent our earliest hominin ancestor or is it something else? Evolution...
Hominins or Hominids
When talking about our ancient anscestors the question often comes up over how we refer to them. Are they hominins or hominids? It's a good question and it depends on how it is being used and what "hominid" branch is being...
Walk This Way
When did our ancestors descend from the trees and walk on two legs instead of four? How exactly did bipedalism develop? We have some ideas but that's all they are - ideas. We may never know, but we can certainly have some fun...

In Part 2 of a 4 Part Series on "The Eclipse of Darwinism", we take a look at "Neo-Lamarkism" as proposed by Jean-Baptiste Lamark. Proponents hoped it would push Darwinian evolution aside as the principal force behind the evolution of species....
The Eclipse of Darwinism
After Charles Darwin's death, the period from the 1880s to the 1920s is known as "The Eclipse of Darwinism". Coined by Julian Huxley, it was a time where alternative theories to explain evolution sought to push Natural Selection aside. ...
Speciation Pt. 2
