Around 9 AM I left the train-7 and walked from 8th Ave to 5th Ave through Broadway. Noticing the crowd of people that hurried to their jobs in the shades of the tall buildings, and particularly by seeing the food delivery guys on the bicycles, the "East Side Story" of Dr. Coppens popped in my mind and I kept thinking all the way about it. The East Side Story goes like this:
Plate tectonics (along with magmatism) has been at work to tear apart the African plate into the Nubian and Somali plates. The speed at which these two plates are diverging is only 6-7 millimeters per year but even at that slow pace, it played its roles in splitting the hominin into the separate species of the humans and chimpanzees (Plate tectonics is not all about splitting things. It also closes and makes things disappear. For instance, it is closing the Persian Gulf and one day there will be no more Persian gulf and the geopolitical maneuvering over its control).
Back to the story.
Around ten to five million years ago the rift valley in East Africa created a barrier between the hominin groups. The chimps remained in the south in their natural environment, that was the forest of the south, while the human-ancestors made small groups who faced new challenges as a result the loss of were favored are not shared
While there are other climate-change stories such as “aquatic hypothesis” and also the results of the soils from the area questions the climate change story (The soil samples in the Tugen Hill region of the rift valley didn’t show a sudden change from forest to savanna during ten to five million years), still, the overall pattern favors a climate change story that caused the evolution of the humans.
Back to the walk on the Broadway:
Walking on Broadway, I thought about the East Side story of human evolution. Ten to five million years ago, the change in climate favored certain traits. Now we are witnessing accelerated are favored
None of the surrounding people walked in the desert or climbed on the trees. They didn’t face the heat, fear of getting hunted, or likewise wasn’t on their way to collect or hunt for food. The hair on the skull was no more needed as all the fancy head-coverings could work better than hair. Brains took the highest work-load in the current environment and the amount of the energy that was consumed
The partnership between males and females was also no more needed as I could see both males and females went to work and there were fewer pairs. If it is happening, it is a slow process and maybe in hundreds of generations; the results become more obvious. But the process has begun (it is happening all the time) and at the risk of repeating myself, the male and female partnerships for food production, storage, and distributions are no more needed. The businesses and corporations are doing all those work more efficiently. You need not go hunting for lunch. They deliver it to you. The development process is going to A decade of schooling was needed acquire be needed been hooked Most of the body is ignored
In the East Side Story, the climate change came to hominin. In the Broadway story, humans are bringing the environmental (also climate change) to themselves. The concrete buildings have replaced forests, grasslands, and deserts. Our work is no more to collect food but to collect money. The division of labor between sexes is politically incorrect (I intentionally used this terminology because I don't expect something like that in the chimps society. Learning about what is politically incorrect or correct is the examples of the behavioral complexity that require education or in other words, it is argued that humans have instincts/genes for grammar, we need to learn the complexity of expressions that vary across cultures even in the same society-... I can go on and on but I think those two examples suffice to ) , digital walls have been erected
