How it relates to other hominin species:
Fossil studies show that wrist morphology of the A. anamensis suggests knuckle-walking, which is derived from African Apes. The A. anamensis hand portrays robust phalanges and metacarpals, and long middle phalanges, much like those shared by humans and apes. These characteristics show that the A. anamensis likely engaged in arboreal living. The A. ramidus preceded the A. anamensis, which was followed by A. afarensis.

A. anamensis and A. afarensis have similarities in the humerus and the tibia. They both have human-like features and matching sizes. It has also been found that the bodies of A. anamensis are larger than those of A. afarensis. Based on additional Hadar afarensis collections, the A. anamensis radius is similar to that of afarensis in the lunate and scaphoid surfaces. Additional findings suggest that A. anamensis have long arms compared to modern humans.

What era they lived (Intro)
A. anamensis is the earliest species of Australopithecus and the most poorly known. The first fossils of the A. anamensis are dated to around 3.8 and 4.2 million years ago and were found in Kanapoi and Allia Bay in Northern Kenya.

More on diet
The palate, rows of teeth, and other characteristics of anamensis dentition suggests that they were omnivores and their diets were composed heavily on fruit, similar to chimpanzees. . These characteristics came from A. ramidus, who were thought to have preceded A. anamensis. Then evidence of a dietary shift was found, pointing to the consumption of harder foods. This was proved by thicker enamel in teeth and more intense molar crowns.
