The Lost One
Thanks. When I started here I wanted to know what people think about the process of evolution, including the conjectures about how life in the sense of evolution began. I found my answers from you in the aggregate sense, and I thank you all for that. While recognizing that many do not believe abiogenesis relates to the process of evolution, I realize that many do believe whatever scientists say about the process.
When majority of students in universities & colleges, enrolled in biology-related courses, they are mainly focusing on current living and extant species of life-forms, not many go the palaeontology-route researching on fossilised remains of different species that differed from current species.
Those that do go, the palaeontology, they have to also study the minerals and rocks and strata of rocks of different geological periods and eras.
But even if biology students don’t seek careers as paleontologists, learning evolution is still essential to all areas of biology fields, as people can still learn how extant species are related to each other.
The Genome Project is one area, where researchers don’t have to look at single fossil. They take samples of DNA of every known extant species of animals, of plants, of fungi, of archaea and of bacteria, mapping every sequences of DNA in each chromosome and mapping of sequences protein-coded genes.
it is similar to have DNA tested for how one person related to another, like between a parent & a child, between siblings, or between close or distant cousins, etc, Some DNA tests can determine where their ancestors come from.
The Genome Project worked on the same principles, but in this areas of research, they are working on species-level.
So, they might compare how the Giant Pandas are related to the brown bears or black bears. Or they might calculate how far back the divergent point between the polar bears and other bears; what they found out that the polar bears are more closely related to brown bears than to the black bears.
Or they find how related are the species of Atlantic salmons to those species in the Pacific Ocean or those in the Indian Ocean. There are more different species within the genus Salmo, 12 of these species lived in the North Atlantic region.
As to Abiogenesis. This is even more specialised field than those in the paleontology field, except that students wouldn’t be studying Abiogenesis, as it is still a hypothesis, so it wouldn’t be available to bachelor-degree courses. Only researchers who advanced knowledge of chemistry in biology, and advanced knowledge in chemistry of Earth environments would be actively research the origins of organic matters (eg the origins of biological macromolecules, such as proteins, nucleic acids, carbohydrates, lipids, and other biological substances).
They (Abiogenesis researchers) are looking at different areas of finding out how these biological compounds can form into the earliest cells.
Whereas Evolution is science, Abiogenesis isn’t, at least not yet. Abiogenesis need more work.
Evolution is about researching the diversity of life, not the origin of earliest life.
