Question
In their laboratory simulations of the early Earth, Miller and Urey observed the abiotic synthesis of: A) life B) complex organic polymers C) coacervates D) amino acids Evolution of populations is most likely to lead to an adaptive solution to an environmental challenge if the cause of the evolution is A) bottleneck effect B) gene flow C) natural selection D) founder's effect Identify which traits are most likely the result of intersexual selection. A) the colorful feathers of a male song bird B) the courtship dance of a male Drosophila C) the large antlers of a male elk D) the larger tusks of a male elephant E) Both C & D are likely. Which statement about the pace of evolution is false? A) Charles Darwin imagined that evolutionary change occurred by the gradual accumulation of small differences (or mutations). B) S. J. Gould and N. Eldridge did not believe that all evolutionary change occurred gradually. C) It now seems likely that some evolutionary changes occurred faster than others due to mutations in developmental genes which made dramatic changes to animal bodies in a fairly short period. D) The work of Gould and Eldridge nullified the work of C. Darwin.Explanation / Answer
47. In their laboratory simulations of early earth, Miller and Urey observed the abiotic synthesis of:
D) amino acid
Urey and Miller used a spark discharge apparatus that demonstrated the formation of amino acids, sugars and other simple organic compounds by recreating yhe condition that might have prevailed on the primitive earth in the laboratory.Their experiment provided a vital proof that the essential building blocks such as nucleotides, amino acids, etc, for the first living organism could have been formed on the early earth or premordial earth.
