One aspect of evolution that is not stressed enough is the impact of consciousness on evolution. Natural selection suggests more of a connection to external factors on biology and DNA, whereas consciousness is an internal factor that can aid survival, through memory and experience, even in less than optimal places, where natural selection may not be your best bet.
I was watching a nature special on TV last night, about elephants. These elephant groups were unique and not what you normally expect of the African Savanna elephants, which are the most studied. One group was in the Rain Forests of the Congo, and the other smaller group, was in the Namib Desert in Namibia's Kunene Region. The latter is one of the driest places in earth. Both groups are not exactly in the most likely places expected of external natural selection. Their survival is due to the intelligence of the elephants, who learn to adapt to these less than normal environments for African elephants.
The rain forest elephants were interesting; paradise with unique hazards, but I was particularly struck by the desert elephants which move in small family groups led by older matriarchs. The mature males tend to be more solitary. They walk, by themselves, day after day; over 50 miles a day, going around the desert to find small pockets of water and/or food, then to another, without over eating or over drinking, to maintain these precious stockpiles for another day. Each year they walk the equivalent of Alaska to Florida. They have a few key places they need to go to gain the needed dried salt spray from the ocean. Their body needs salt to survive.
They have very strong memories and amazing navigation skills. They need to keep moving to find the sparse food and water sources their entire life; 40 years. They also circle back to meet up with their mate and her group, to see if they can have a date. Their breeding depends if the female thinks her baby can survive; does she anticipate have enough water to make the needed milk. This is an impossible landscape for any family situation, yet they all persist.
The females, babies and younger elephants so the same, in terms of the long constant walk, with an older matriarch remembering all the routes and safe spots, needed for food, water and salt, year after year. The younger females will learn from her and lead someday. Even one day old babies will need to keep up the pace or not survive. Her mother and aunts will help the baby. These elephants were partiality naturally selective, but they also learned to adapt and have selected this environment based their learned memories, taught from generation to generation.
This is similar to humans, in the sense we do not just rely on natural selection. We can also make manmade selections. We can farm our own selected food crops. and we have control over the selective breeding of pets and farm animals; conscious selection. Humans have ended up all over the earth, even where there are a wide range of natural selective parameters; not perfect, using intelligence to adapt and even thrive.
Civilization and farming would have been a conscious choice, not to be fully dependent on nature's bounty based on natural selection, since natural food stocks run out if too many humans use only natural places. Instead, consciousness allowed a way to provide perpetual food in one good location, which is not exactly natural or based on natural selection. The Bible symbolism is about the rise of human consciousness to the level of being up to the task of life, in a more self sustaining way.
