What does Australopithecus anamensis?
Australopithecus anamensis individuals had thickly-built, long, narrow jaws with their side rows of teeth arranged in parallel lines. Their strong jaws combined with heavily enameled teeth suggest Au. anamensis have been found were forests and woodlands that grew around lakes.
Where is Australopithecus anamensis?
Kenya
Australopithecus anamensis was found in Kenya, specifically at Allia Bay, East Turkana.
Who named Australopithecus anamensis?
DISCOVERY AND GEOGRAPHIC RANGE Multiple paleoanthropologists (most notably Meave Leakey and Alan Walker) are credited with the discovery of Au. anamensis material. The species name refers to the Lake Turkana area of Kenya where the fossil sites of Kanapoi and Allia Bay are located (see Figure 10.2).
When was Australopithecus anamensis found?
1965
Australopithecus anamensis (or Praeanthropus anamensis) is a stem-human species that lived approximately four million years ago. Fossils have been excavated in Kenya and Ethiopia. The first specimen was discovered in 1965 near Lake Turkana, followed by excavations in 1987 by Allan Morton.
Did Anamensis use tools?
Scientists have discovered evidence that human ancestors were using stone tools and consuming meat from large mammals nearly a million years earlier than previously documented. The bones are about 3.4 million years old and provide the first evidence that Australopithecus afarensis used stone tools and consumed meat.
How did Australopithecus anamensis adapt to their environment?
They also had small canine teeth like all other early humans, and a body that stood on two legs and regularly walked upright. Their adaptations for living both in the trees and on the ground helped them survive for almost a million years as climate and environments changed.
Where remains of Australopithecus were found in Kenya?
Lake Turkana
Video. Discoveries at Lake Turkana reveal information about the history of human evolution. In 1995, National Geographic Explorer-in-Residence Meave Leakey and her team made a very important discovery at Lake Turkana, Kenya. They found fossils of what turned out to be an Australopithecus anamensis.
How did Australopithecus survive?
What did the Australopithecus afarensis invent?
New finds from Dikika, Ethiopia, push back the first stone tool use and meat-consumption by almost one million years and provide the first evidence that these behaviours can be attributed to Lucy’s species – Australopithecus afarensis.
What skills did the Australopithecus develop?
Fossils show this species was bipedal (able to walk on two legs) but still retained many ape-like features including adaptations for tree climbing, a small brain, and a long jaw.
What kind of food did the Australopithecus eat?
Au. afarensis had mainly a plant-based diet, including leaves, fruit, seeds, roots, nuts, and insects… and probably the occasional small vertebrates, like lizards.
How old was the Australopithecus anamensis when it lived?
Australopithecus anamensis is a hominin species that lived approximately between 4.2 and 3.8 million years ago. Nearly one hundred fossil specimens are known from Kenya and Ethiopia, representing over 20 individuals.
What kind of teeth did au.anamensis have?
Unlike the parabolic tooth arrangement in the jaws of later hominins, Au. anamensis had an apelike, U-shaped dental arcade wherein the cheek teeth are nearly parallel (see Figure 10.3). Their jaws were also prognathic and their canines were larger than descendent species.
How are Australopithecus anamensis similar to Ardipithecus ramidus?
Tooth size variability in A. anamensis suggests that there was significant body size variation. In relation to their diet, A. anamensis has similarities with their predecessor Ardipithecus ramidus. A. anamensis sometimes had much larger canines than later Australopithecus species.
What kind of food did Australopithecus anamensis eat?
Australopithecus anamensis individuals had thickly-built, long, narrow jaws with their side rows of teeth arranged in parallel lines. Their strong jaws combined with heavily enameled teeth suggest Au. anamensis individuals may at times have eaten hard, abrasive foods, but they likely were plant-eaters in…
