PLEASE HELP !! As scientists have investigated evolution from a variety of fields, they have found that some of Darwin's original ideas were inaccurate or incomplete. The explanation provided by evolution was updated each time to reflect the new information they found. What does this suggest about the theory of evolution?
Possible answers: A. It has become a stronger and clearer theory as new information is collected. B. Scientists are getting closer to proving evolution to be true so it could be called a law. C. The idea of evolution must be false if scientists have had to make changes to Darwin's ideas. D. It has become less trustworthy theory as changes have been made to it.
Hypothesis and theories cannot be proved, they can only be disproved. One reason why the Theory of Evolution is a fact to this date, is that it has not been disproved. It is true that Darwin provided the first true mechanism, which by means of natural selection, and it is true that some other scientists after his time revealed new phenomena he never imagined - from the sequencing of DNA, embryology, genetics, paleontology and proteomics - that postulate additional mechanisms; none of the discoveries, however, disproved the theory, they only refined it. An excerpt from his famed book, On The Origin of Species calls for an attention, wonder and awe: There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved. - Charles Darwin
Why is carbon so abundant in living things when oxygen is the most abundant element on Earth? Carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures. Carbon atoms are found in compounds that are solids at room temperature whereas oxygen atoms are found in compounds that form gases Carbon atoms have lower mass than oxygen atoms, which keeps the masses of living things within desirable limits. Carbon atoms are more stable than oxygen atoms, which allows living things to have more stable compositions.
