So, it’s like the theory of evolution first then you hypothesize abiogenesis later on to support the theory of evolution. IOW, abiogenesis “was part of the theory of evolution.”, right?
We view the evolution of the universe in five phases:
[1] Material evolution comes first, in which the galaxies, stars, and chemical elements and minerals formed). The Standard Model of cosmology addresses this.
[2] This is followed by chemical evolution, in which the atoms and organic molecules organized into the first life, or abiogenesis.
[3] Then comes biological evolution, in which the tree of life evolves from this unicellular common ancestor.
[4] Then comes psychological evolution, or the appearance of consciousness and increasing intelligence including human intellect.
[5] And finally, cultural evolution, as we go from animal skins and tents or igloos to the moon and back.
These problems have not been and will not be solved in that order.
The first of these to be solved was [3], biological evolution, in the mid 19th century, which also contributed to [5] as man began digging (literally)- when did man first settle, or sail the oceans, or use language, tools and fire, or invent religion as paleontologists and archeologists continue to explore these mysteries..
Then, [1] was solved in the 20th century.
Presently, [2] is being solved with abiogenesis research, which is progressing at a rapid pace.
The problem of the emergence of consciousness, [4], will probably be the most intractable.
The insistence to resolve abiogenesis before evolution is a pointless and arbitrary one. We solve these problems as we can.
that would make Lucy a chimp and not a human.
Lucy could not have been a chimp. She was bipedal. She walked upright. Brachiating apes (knuckle walkers) have their foramen magnum, the hole in the skull for the spinal cord to pass in and out of the head located between the occipital (back) and inferior (bottom) aspects of the skull, which is typical for brachiating animals whose spinal cords are more parallel to the ground than ours. Obligate tetrapods (animals vitually always on all fours) like the wolf skull shown below, have theirs even more posteriorly
Lucy's foramen magnum, like ours, is on the inferior (bottom) aspect of the skull, which is typical of animals who walk upright and whose spinal cords are more perpendicular to the ground. Compare here skull and the location of her foramen magnum to that of the chimp and gorilla skulls below.
Lucy is clearly a transitional stage between chimplike creatures with small cranial capacities (around 450 cc), a brow ridge, and a snout similar to modern chimps, but who stood upright,and man, with a brain about three times as large - a missing link if you like.
