Early Hominins are the hominin species recognized as the first species of the genus homo and lived approximately 2.5-1.8 million years ago.

Between 2.5 and 3 million years ago, the genus Homo initially made its appearance. For a long time, Homo habilis fossils were thought to be the oldest specimens of the genus Homo for a long time, but in 2010, a new species dubbed Homo gautengensis was found and maybe older.

Homo: a genus. The earliest remains of our own genus, Homo, date to 2.3 mya and are located in East Africa (Kimbel et al. 1997). These early individuals share the same size of the brain and body as Australopithecus, but their molar teeth differ, indicating a shift in nutrition.

The genus Homo belongs to the family Hominidae (order Primates), and it is distinguished by a relatively large cranium, limb anatomy that is suited to a habitual upright position, and a bipedal walk.

From the markings that you had written and erased on your graph, it seems that you already have an idea of what you're supposed to do. Is it that you're having trouble scaling your graph on the provided sheet given the particular data? Or do you have a conceptual question with respect to the instructions?

I've provided the image of the graph according to my understanding of the instructions as stated in 1 and 2, and I've also attached the corresponding Excel spreadsheet that I used to create the graph. While the blank grid that you've attached doesn't scale identically to my graph, it should be possible to transpose the necessary elements into your grid to an acceptable approximation.

That said, please feel free to let me know if you have any clarifications, comments, or questions.
