Question

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 above?

(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.

Answer 1

(D) Earlier genome analysis established genetic links between early humans and chimpanzees.

Step-by-step explanation:

Genome is a genetic code, which has all the hereditary information of a being, and is encoded in DNA. It is the set of all the different genes found in each nucleus of a given species. In haploid chromosomal endowment, a nucleus has only one genome.

Through this analysis, it is possible to map the ancestry and genetic evolution of all species, for this reason we can state that according to the information given in the above question, genomic analyzes previously made established genetic links between primitive humans and chimpanzees, for example. It was possible to conclude that the ancestors of humans and chimpanzees may have hybridized to produce the lineage from which modern humans developed.
