•
Laetoli footprints
•
Tanzania
•
first evidence of                walking by early hominin
•
preserved in                  layer
•
not only has hominin footprints but other               
•
lions
•
antelope
•
       square kilometers
•
1894 reported in scientific literature
•
Oscar             
•
Austrian geographer
•
was looking for the source of the          River
•
he got lost
•
collected fossils
•
took them back to Germany, at Berlin                      Museum
•
1940s
•
more fossils collected
•
more scientists wanted to come
•
Louis and Mary              was planning a German/British research trip, but was cancelled because of the war
•
         Mary Leakey came back
•
collected fossils
•
first hominin fossils
•
LOH 4
•
prototype for Australopithecus                   
•
3.85 and 2.95 million years ago
•
Lucy's species
•
1978 footprints
•
first evidence of                posture and bipedal evidence in hominins
•
3.5 or 3.6 million years ago
•
the more the prints are exposed
•
there could be more than        individuals
•
probably four individuals with same stature and same height
•
the entire footprint trail is almost 27 meters long and includes impressions of about 70 early human footprints
•
1978 Paul            joined Leakey's team and found the 27 meter-long footprint trail
•
the early humans that left these prints were bipedal and had big toes in line with the rest of their foot
•
his means that these early human feet were more human-like than       -like
•
apes have highly                    big toes that help them climb and grasp materials like a thumb does
•
the footprints also show that the gait of these early humans was         -strike followed by toe-off, the way modern humans walk
