TEDx Talks
This talk was given at a local TEDx event, produced independently of the TED Conferences. Anthropologist Dr. Carl Lipo says everything we thought about Easter Island’s famous collapsed civilisation is wrong. He suggests Bermuda can learn lessons from that catastrophe about long-term survival on our own isolated, water-parched island.

I currently serve as an Associate Professor at California State University, Long Beach (CSULB). I am part of the faculty of that forms the basis of a Program in Archaeology and a founding member of IIRMES, a multi-disciplinary institute for the study of materials, environments and society. At CSULB, I teach classes in Introductory Archaeology, World Prehistory, Eastern North American Prehistory, Artifact Analysis, GIS, Statistics, Method and Theory, Foundations of Anthropology Field Research Design, Geophysical Techniques, and the Scientific Study of Origins. My research focuses on the use of evolutionary theory to generate scientific explanations about human cultural change in the archaeological record. I see this focus as a critical challenge for the social sciences and that our ability to be able to due this task vital to our future. My perspective is fairly idiosyncratic to my background but lodged in the philosophy of science and evolutionary biology. You can view some of my recent work (here) to see a little into how I think about the world. My recent studies include the development of theoretical models and the construction of methods for studying patterns of change caused by cultural transmission and the process of natural selection in cultural systems. In addition, I have interests in remote sensing to efficiently and non-destructively study the record. This work includes the use of magnetometry, resistivity, conductivity, thermal imagery and ground penetrating radar. My field research has taken me from the Mississippi river valley to Easter Island to California and coastal Guatemala.

Brilliant presentation.
Ellie Marie Carlock
Great presentation. I would have loved to listen about findings about the moai top hats and also who the team of Japanese were that came post 1950 to stand moai up

due to its isolation from the rest of the world by 2000 km of sea, i think its likely they got trapped and as the sea rose they fled to the mountains, easter island being the tip of the mountain, the statues face in to say we are all here, you have to remember if they sailed there they could sail back or elsewhere unless sailing was not an option e.g either did not have the tech or resources. it makes sense to me what robert schoch suggests as an electromagnetic storm created the flood (check joe rogan podcast with him included)

I'm rapanui, and I can say that the Moai are monuments built for commemorate our ancestors, they are like really big cemetery sites but for kings and other relatives of the royal family.
Russ G
OK, am I the only one who concludes that the Moai, rather than being a waste of human labor, might actually be the BYPRODUCT of those rock gardens? IOW, they were what was left over after they quarried the minerals they needed? Carving the statues might have simply provided some motivation for what would otherwise have been a task of pure drudgery.
Blue
If people got there and started to make the statues, why aren't there similar statues elsewhere?
MrGigigigia
It's easy. The statue fall on their own over time.
blanca roca
Interesting stuff! What about the destruction of the trees which was supposed to a big thing?
Josh Young
I think maybe those tools are coconut openers 😕
Samantha Laurie
The part that he did not say is the stone is not native to Easter Island it was put there
Hammer Of Crom
Many of the statues you see as heads actually have bodies that have sunk underground. Basically what we see is the upper 30-50%. So these statues are far larger than what people commonly believe.
Bertie Pimplebum
If you were a passing alien, where would you land? Easter Island statues depict what they looked like.
Robert La Mont
Thank you!  I have read these things but this is a great presentation.
Chris McMahon
I don't see how they were so successful at much except erecting statues. Not sure if I buy the politically correct theory that Europeans we're always the horrific cause of all the bad in the world. Sure, they were no saints. But somehow we now cannot speculate that an indigenous society could do anything bad.

Hello Ted,do u have some more footage of u guys walking the statue . looks so good and amazing

Move over Pluto - Is there a 9th planet in our Solar System? Dr. Malhotra and other planetary scientists have discovered the theory of Planet 9 after noticing that something was exerting a gravitational force on objects in the Kuiper Belt – an area of comets, the dwarf planet Pluto and huge icy objects beyond Neptune that encircles the whole solar system.

An esteemed professor of physics, member of the National Academy of Sciences and of the American Academy of Arts and Sciences, Dr. Malhotra is an esteemed astrophysicist. She has examined a wide variety of topics, spanning from extrasolar planets to the meteoric bombardment history of the planets. She has revolutionized our understanding of the formation of “Plutinos” and other small planets, as well as the orbital migration of giant planets. She cannot help us understand why man-buns are in style.
