    WHY WOULD RAPID ADAPTATION BE REQUIRED FOR A RAPID EVOLUTION? GEOLOGY can power energy transformation in mitochondria!

    It was the rapid climate change of the Rift zone caused by plate tectonics. Take a look at this excerpt from one of my cites below.

    “The Turnover Pulse Hypothesis purports, the Variability Selection Hypothesis requires climate change on a much more rapid time scale and without consistent pressure in the same direction. It states that dramatic and frequent climate changes drove adaptations that enabled individuals to cope with a wide range of environmental conditions. These frequent climate changes thus drove hominins to evolve ways to better adapt to a variable environment. Indeed, the fossil record reveals two methods adopted by different hominin species: brain expansion to think and manage environmental stresses, and massive jaws to eat anything, whatever the conditions.” It appears most of that food source was in the waterways from the oceans on the flooded coasts.

    “An example of such rapid climate change is El Niño-Southern Oscillation (ENSO), which currently has a major influence on East African climate. However, for there to be a strong ENSO, there needs to be a strong east-west atmospheric circulation called Walker Circulation. About 2 million years ago, Walker Circulation intensified to its modern level and may mark the start of ENSO. This would have resulted in extreme annual variations in local and regional climates from 2 million years ago onward, which correlates with the first appearance of Homo erectus and the last occurrence of Australopithecus africanus. Another example is the periodic extreme climate change that can come from orbital forcing, which is the wobble of Earth on its axis of rotation and orbit around the sun. Geologists have known for decades that orbital forcing controls the waxing and waning of ice ages, but we now realize that it may have profoundly affected tropical climates as well. The excellent stratigraphy available for the East African sites has allowed researchers to document the link between orbital forcing and ancient lake levels.” I spoke about how orbital forcing played a major role in Factor X as well in my Webinar.

    “No doubt rapid climate changes played a major role in speciation, causing adaptive responses to severe shifts in moisture availability and the consequential changes in the ecosystems. The onset of Walker Circulation around the end of the Pliocene seems to have modified the response throughout the continent. For example, in southern Africa, the mixture of woodland-dominated and grass-dominated plants present through the Pliocene is replaced at that time by a system dominated by grassy plants, as Phil Hopley of University College London in the United Kingdom and colleagues have shown.”

    Looks like the idea still is working for us. Let's look further at the plate tectonics of the Rift Zone.

    Tectonics and the building of the human cradle:

    “Recent studies show that tectonics modulates local climate, especially in East Africa. The formation of the East African Rift Valley between 10 million and 5 million years ago forever changed Africa’s landscape and climate and, it seems, the course of human evolution. In less than 5 million years, East Africa went from a relatively flat area with abundant rainforests to a region of extreme topography. As the rift opened, a region of mountains, plateaus and deep rift valleys formed, creating the so-called cradle of humanity.

    The newly formed East Rift shoulder, or mountain range, prevented moist air from the Indian Ocean from passing over East Africa and significantly dried the other side of the mountains. This combination of topography and aridity shifted vegetation, which produced a climate that varies from cloud forest to desert scrub across the rift. On a local scale, Rhonda Quinn of Rutgers and colleagues have shown that in Koobi Fora in Kenya, grasses appeared later than in the rest of the region, likely driven by tectonic changes that altered the local hydrology. Without considering tectonic changes and the evolution of the East African Rift, sedimentary records in this area might be misinterpreted as primarily forced by global climate change. On a regional scale, too, the impact of tectonics is not straightforward. This is clearly illustrated by the large lakes of East Africa, which developed as the East African Rift developed.

    We’ve known that the rise of the mountain ranges caused aridity changes for a while, but the relationship between orbital forcing, the tropics, and moisture availability in the East African Rift Valley is new and quite exciting. It also sheds light on potential causes of changes in hominin evolution.

    Water is rare in northern Kenya today and this water seen on the recent expedition to Suguta Valley disappeared within two days. Researchers had to use helicopters to reach the sites.”

    So far, all the things we need to set the table are present for us to come from transitional apes.



    So what unifies climate and plate tectonics? Pulsed Climate Variability Theory: NOW BIO-ASTROPHYSICS ENTERS the story!


    “What’s needed, then, is a hypothesis that combines tectonic forcing with climate variability, thus linking orbital variation and the new topography. Enter the Pulsed Climate Variability hypothesis as suggested by Martin Trauth of the University of Potsdam in Germany and Mark Maslin.

    Over the last 3 million years, the East African Rift Valley has become more arid, but we now know that this long-term trend was punctuated by short episodes of alternating periods of extreme wetness and aridity. Using detailed analyses and excellent stratigraphy, John Kingston of Emory University in Georgia and colleagues have found an extreme change in lake levels in the Baringo Basin in Kenya between 2.7 million and 2.5 million years ago at a precessional scale (about 21,000 years).” I talked about precessional changes as well, in my Factor X webinar in May of 2012. We also have the shield volcano located in this region that likely walled off chimps from their forest.

    “Such periods of extreme climate variability occurred three times in the last 3 million years. Trauth and his colleagues suggest that each of these periods coincided with a major global climate change during which East Africa became more locally sensitive to orbital forcing at precessional scales. This resulted in rapid shifts from wet to dry conditions, as moisture from the tropics alternately was available or denied to the rift valley, depending on orbital configurations. These periods of “pulsed climate variability” are characterized by the precession-forced appearance and disappearance of large, deep lakes in the East African Rift Valley. These lakes were huge and deep — well over 1,000 square kilometers and 300 meters deep. Trauth and his colleagues are continuing this work on large paleolakes found in the Suguta Valley in northern Kenya by trying to establish how quickly these large lakes appeared and disappeared. Their results show that the scale of Paleo-Lake Suguta is astonishing — only 13,000 to 10,000 years ago, there was a lake 300 meters deep covering 1,600 square kilometers.

    Significantly, over the last 3 million years, such periods are focused at times of major global climatic transitions, such as the intensification of Northern Hemisphere glaciation 2.7 million years ago, the onset of Walker Circulation 2 million years ago, and the mid-Pleistocene Revolution 1 million years ago — during which the ice ages started to become more intense and longer. These periods of pulsed climate variability may have provided a catalyst for evolutionary change and driven key speciation and dispersal events among mammals and hominins in Africa. In particular, hominin species seem to differentially originate and go extinct during periods of extreme climate variability. Although representing less than a quarter of the total period of highly variable East African climate, or pulsed climate variability, 12 out of the 15 known hominin speciations occurred between 5 million and 500,000 years ago.” 12 for 15 is a pretty good batting average.

    “Despite the aridity of modern East Africa, in the past, much of the region has been covered with large lakes that have come and gone. Many of these paleolakes correlate with key steps in human evolution. One of the tasks of the recent expedition to the Suguta Valley was to map all of the old lake shorelines.” This means that hydrology and water played a massive role in forming humans. Many people like to lean on the aquatic ape theory because it addresses morphologic changes that the bone collectors have been stumped by. I however think the theory is too dumbed down for many reasons. However, the one point that I think is no longer debatable is that humans evolved around water and even left Africa using the coastal waterways. Most of human civilization is tied to water supplies.

    You can check out these Rift Zone water features if you open some cites below

    “Thus, the evidence seems to be leading us to believe that not only is highly variable climate associated with evolutionary innovation, but that pulsed climate variability is a mechanism for focused periods of innovation, whereby orbitally forced rapid climate changes are separated by periods of relatively reduced amplitude change. Furthermore, the evidence suggests that such climate changes would never have had the same extreme effect if it were not for the tectonic disruption, as the East African Rift formed.”

    “Tectonics can thus be seen as a fortuitous intervention in human history, allowing orbitally forced tropical moisture changes to become a potent focusing mechanism in our evolutionary pathway. Local climate responses to these tectonic changes were likely amplified by the onset of Walker Circulation and modulated by precessionally forced variations in moisture availability, at least in East Africa. As a result, speciation also seems to have been earlier, and maybe even faster, in eastern Africa than in more stable southern Africa. However, the climate of southern Africa is not well-defined for the late Cenozoic, and we are just now beginning to assemble a detailed history of this complex region. The “Pulsed Climate Variability” hypothesis thus integrates climate variability with major climate events and provides a potential explanation for the rapid evolutionary innovation during this time period. Whether this directly led to speciation in East Africa, and later migration out of Africa, is still a major question. ” If form follows function then one can immediately see why a biologic organism would need to rapidly become sensitive to its new environmental conditions. This is why we evolved a leaky gut and a rapidly adaptable immune system. The size effect of both was to gain a large brain because of what nutrients were contained in those new water sources.
