Which kind of DNA should provide the best molecular clock for gauging the evolutionary
relatedness of several species whose common ancestor became extinct billions of years ago?
a. that coding for ribosomal RNA
b. intronic DNA belonging to a gene whose product performs a crucial function
c. paralogous DNA that has lost its function (i. e., no longer codes for functional
gene product)
d. mitochondrial DNA
e. exonic DNA that codes for a non-crucial part of a polypeptide

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

in addition to spreading humanist ideas, erasmus has contributed to criticism of corruption in the church.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
