Question # 13. Explain briefly the orthogenesis and orthoselection in evolution.
Can you please help me with this question
The theory of evolution was controversial when it was first proposed in 1859, yet within 20 years virtually every working biologist had accepted evolution as the explanation for the diversity of life. Explain in at least 50 words why.
Which of the following is least reasonable regarding the Urey-Miller experiment?
Group of answer choices
The experiment was an important breakthrough in the study of the origin of life.
The experiment conifirmed that several of the key molecules of life could have been synthesised naturally on the primitive Earth.
The amino acids and other molecules produced in the experiment, and possibly present in the early atmosphere, could have participated in 'prebiotic' chemical processes, ultimately creating life.
This experiment, and others which followed, suggests that simple biologically significant molecules can evolve naturally under sets of conditions that may have existed not only on early Earth, but potentially elsewhere in the solar system and beyond.
The experiment was the first demonstration of abiogenesis (life from non-life).

Reproduction is required for both chemical and biological evolution. Both chemical and biological evolution are defined by change over time. Purpose of Miller-Urey experiment was to answer the question: can chemistry give rise to complex molecules required for life? The Miller-Urey experiment showed that chemistry can give rise to the molecules required for evolution of life.arrow_forwardWhat are the implications of cellular and molecular biology for spontaneous generation and the hypothesis of evolution? please just answer in a short paragraph, no need to be long and just a simple answer (easy to understand)arrow_forward

- Imperial China during the Ming dynasty (1368-1644 CE) could conceivably have started the Scientific Revolution before Europe; its failure to do so might have resulted (at least in part) from each of the following factors except: Chinese colleges were under Imperial control, not independently-chartered as in Europe military expenditures were diverted from ship-building to land-based armed forces foreign trade was dominated by the Imperial Navy, with no profit motive for merchants European sailing vessels of that time were much larger than Chinese treasure ships Chinese religion was polytheistic, while the central government at that time was strongarrow_forwardSystematics and Evolution Which among the evolutionary factors are random processes? Which among them are not?arrow_forwardOne of the simplest definitions of a life-form is anything with the capacity to reproduce and regulate itself. Before life began, the complex organic, or hydrocarbon-bearing, molecules that makeup RNA and DNA, the building blocks of life, must have formed. No one knows exactly how life is formed from these molecules, but many ideas have been put forward. As you enter this area, go toward the large video screen on the right and explore the “Life at the hydrothermal Vents” label deck. Some scientists theorize that life begins at deep-sea vents. Find three lines of evidence to support this claim.arrow_forward
