Question

When Darwin first proposed his theory of evolution by natural selection, the field of
genetics did not yet exist. In what way does genetic science now contribute to the
study of evolution?
a
Scientists can create organisms that were extinct using DNA from fossils and better understand how they evolved.
b
Scientists can determine evolutionary relationships among living species by
comparing amino acid sequences coded for by DNA.
c
Scientists can compare the DNA from fossils in rock to determine evolutionary relationships among extinct species.
d
Scientists can use genetic engineering to carry out the process of evolution over just months instead of millions of years.
