Question
In 800 words, describe the emergence of biological organisms in all their complexity from basic material origins to the world we see today. In your description, be careful not to use skyhooks and base your descriptions on evidence, not just proposition. This means that you should be highlighting how science has come to understand what you’re saying rather than relying solely on philosophy. Remember to be careful in your logic as we spoke about in class. It is not science to search for examples, but to search for evidence against. Single examples can be support but are not what we ‘search for’. Include at least the following elements in your description:
Early molecules and self-replication
Black smoker vents
Protein functional changes and the link to genetic evolution
Evolution from the perspective of DNA.
Emergence of functions that contributed to selection toward eukaryotes (make sure to explain the process not only components)
Emergence of functions that contributed to selection toward multicellularity.
Evolution of Sight
Transition of organisms to land
Coupled evolution of organisms and their environment using the Globin variations example
Human evolution and the integration of culture as a version of phenotypic plasticity embedded in brain evolution.
Then, close on what this means for the future of humanity as you have reflected on up to this point. Spend approximately 300-400 words on this part for a grand total of 1100-1200 words.
Explanation / Answer
Biological organisms in the existing world is tthe complex and hierarchical system, where it extends from the simple cellular levels to the higher ecological levels. Where this hierarchial biological is based on the previous life forms, thus it represents the evolution of the levels to higher life forms from lower evels. As well as these biological life forms still exist because of the replication and reproduction which involves in the formation of the new life form, basically for the lower level life forms they involve in the self replication and the higher level by reproduction. The black smoker vent is nothing but the underwater volcanos formed by the moment of thr tetronic plates, these black smokers emitts hydrothermal fluids composed of sulphide minerals black in colour. They are about to be 7000 F but due to the high underwater pressure they will not burn. There these black smoker vents were surrended by various types of life forms, scientists explains this because of the chemical reaction between these hydrothermal fluids and the seawater results in the existence of these life forms Basically all the DNA function depends on the proteins, wheree these protein complexes held these dna in a compact structure, if there is any change in the protein complexes it will leads to the genetic variations and also may be evolution. The major function that leads to the evolution of the eukaryotes were thw formaton pf the nucleus and the miochondria as well as the endomembrane system, thus also they were explined in the inside-out model of the eukaryotes. Here the same evolution of the multicellular organisms depend on the genetic identity and the genetic information, this genetic blueprint plays as the key to the co-ordination and the formation of the cellular actions to evelope into a multicellualr forms. The evolution of the eye sight is also found in the unicellular level as the photoreceptors termed as the "eyepots", they are developed into a fully grown eye in all the multicellular level organisms. The functional unit of the eye is the "photoreceptor cells". The invasion of the life forms on the land is the major breakthrough in the evolution of the vertebrates. This evolution was caused by various marphological changes in the previous live forms and also certain unfvourable climatic conditions as well as the aquatic conditions are responsible for the evolution. The important evolution in the biological forms in land is the evolution of humans, this was because of various physiological, morphoogical, genetical and such more factoral changes. It is that the humans were evolved from the ancessestors chimpanzee. Then the culture has been develpoed by the human and its was explained in the term cultural brain hypothesis. This was also a major evolution line in the term of humans and the surviving was also a factor that leads to the formation the culture. Thus the human is in the top of the biological evolution, this great evolution was depends on the major phenotypic plasticity, though this phenotypic plasticity is more important for the immobile life forms, movabl life forms also involved in this process thus it helps in evolution of the life forms from the lower level to the higher level life forms. Further, it was a big deal in the future of the human race, more over the humans are being evolved as in the terms of gaining knowledge as well as discovering new life forms. Thus the humans are being evolving by the help of various factors such as genetical modification and some belives that the human has been stoped evolving. However there are some life forms which are in the edge of extinction and it is the major role to save those from being extinct.
