The ability to analyze genomes — sequences of DNA — has grown more and more
sophisticated. Scientists are able to examine the biological past in finer detail and with
greater accuracy. A new analysis of the genetic links between early humans and
chimpanzees has led to a hypothesis that the two species diverged more recently than
previous estimates indicated. This gives credence to a very startling new theory: the
ancestors of humans and chimpanzees might have hybridized to produce the lineage from
which modern humans eventually developed. What can be inferred from the statements
A) Hybridized species combine the best of both lineages.
b) Political and religious pressures will affect the course of future research.
c) Future research will enable scientists to determine the exact characteristics of this hybrid
ancestor of modern man.
d) Earlier genome analysis established genetic links between early humans and chimpanzees.
e) Human DNA is more complex than that of chimpanzees.
