Student Lab Key Lesson 3: Naledi Jigsaw 77. Lesson 3 Author’s note Introduction Page The validity and importance of the theory of biological evolution runs strong throughout the topic of biology. Evolution serves as a foundation to many biological concepts by tying together the different tenants of biology, like ecology, anatomy, genetics, zoology, and taxonomy. It is for this reason that evolution plays a prominent role in the state and national standards and deserves thorough coverage in a classroom. A prime example of evolution can be seen in our own ancestral history, and this unit provides students with an excellent opportunity to consider the multiple lines of evidence that support hominid evolution. By allowing students the chance to uncover the supporting evidence for evolution themselves, they discover the ways the theory of evolution is supported by multiple sources. It is our hope that the opportunity to handle our ancestors’ bone casts and examine real molecular data, in an inquiry based environment, will pique the interest of students, ultimately leading them to conclude that the evidence they have gathered thoroughly supports the theory of evolution. -

LISA HOLMGREN visual art Tiramisu bathtub, blonde, tiramisu 160 x 70 x 70 cm, 2019 A blonde man is placed in a bathtub filled with tiramisu. He calls out “Tiramisu!”, which can be translated to “Pick me up”. By stating the obvious he is simultaneously begging for someone to get him out of there. I am aiming to convey a state of ambivalence towards notions of excess, consumer culture and isolation. Människan är född fri och överallt är hon i dojor marble, wingnut, threaded rod, shoelaces 22 x 30 x 12 cm, 2018 During the hot summer of 2018 I spent three weeks at a stone carving workshop. I wanted to create and image of an object of desire which pose a physical threat to our ability to move. The rising star cave by Niklas Hoffmann Wahlbeck The “Rising Star Cave” is located in the Malmani Dolomites in South Africa. At the very end of the rising star cave, 30 meters underground, lies the “Dinaledi” chamber. It can only be reached through a narrow and steep crack that is 12 meters long with an average width of just 20 cm. In the Sotho-Tswana languages, “Dinaledi” means “Chamber of Stars”. In late 2013 a small expedition reached the Dinaledi chamber and found the bones of one owl and of 15 humanlike individuals. Tests have shown that the bones are around 300.000 years old. It seems like they were once deliberately placed in this far off cavern, indicating some kind of burial rite. They belong to a now extinct species of homini called “Homo Naledi”. -

This Face Changes the Human Story. But How? NALEDI FOSSILS | News This Face Changes the Human Story. But How? Scientists have discovered a new species of human ancestor deep in a South African cave, adding a baffling new branch to the family tree. By Jamie Shreeve, National Geographic Photographs by Robert Clark PUBLISHED SEPTEMBER 10, 2015 + http://news.nationalgeographic.com/2015/09/150910-human-evolution-change/[9/18/2015 7:27:50 AM] This Face Changes the Human Story. But How? While primitive in some respects, the face, skull, and teeth show enough modern features to justify H. naledi's placement in the genus Homo. Artist Gurche spent some 700 hours reconstructing the head from bone scans, using bear fur for hair. PHOTOGRAPH BY MARK THIESSEN, NATIONAL GEOGRAPHIC A trove of bones hidden deep within a South African cave represents a new species of human ancestor, scientists announced Thursday in the journal eLife. Homo naledi, as they call it, appears very primitive in some respects—it had a tiny brain, for instance, and apelike shoulders for climbing. But in other ways it looks remarkably like modern humans. When did it live? Where does it ft in the human family tree? And how did its bones get into the deepest hidden chamber of the cave—could such a primitive creature have been disposing of its dead intentionally? This is the story of one of the greatest fossil discoveries of the past half century, and of what it might mean for our understanding of human evolution. Chance Favors the Slender Caver Two years ago, a pair of recreational cavers entered a cave called Rising Star, some 30 miles northwest of Johannesburg. -
What's New in Hominid Evolution
What’s New in Hominid Evolution CHARLES J. VELLA, PHD SEPTEMBER 28, 2015 Oldest fossil mammal: 165 MYA – mother of us all Australopithecines: A 2 Million year span of existence Genus Australopithecus had six, maybe seven species in it, depending on who you believe. Now that is an astonishingly successful genus as far as evolution goes. The oldest yet found is A. anamensis, which is more than 4m years old. The youngest is A. sediba which is about 1.9m years old. That’s a life span of nearly two million years between these species. New Species: Australopithecus deyiremeda (Holotype BRT-VP-3/1): 3.4 MYA Australopithecus deyiremeda (“close relative”) lived about 3.4 million years ago in northern Ethiopia, around the same time and place (35 km from Hadar) as Australopithecus afarensis. Lower jaw was beefier, and the teeth smaller, than Lucy’s species Yohannes Haile-Selassie, et al., 2015 Ethiopian Jaw Bone (LD 350-1): 2.8 M – oldest genus Homo Jaw bone fossil discovered in Ethiopia is oldest known human lineage remains Around 400,000 years older than previous discovery of homo lineage, 2.8m-year-old jaw and five teeth was found on rocky slope in Afar region, at a site called Ledi-Geraru, 40 miles from where Lucy was found. The picture that emerges from the fossil record is that 3m years ago, the ape-like Australopithecus afarensis died out and was superseded by two very different human forms. One, called Paranthropus, had a small brain, large teeth and strong LD 350-1 mandible jaw muscles for chewing its food.
