Just as significantly, a growing number of scientists believe that animal testing, though useful, is far from ideal given the multiple genetic differences between the species.
But Dr Paabo's work also illuminates the differences between the species.
There were differences between the species, however.
Thus, biofilm formation may play a key role in virulence differences between the species.
We discuss differences between the species that may explain their opposite reaction to video images.
The same polymorphisms were also genotyped in 21 wolf blood samples to explore potential genomic differences between the species.
"The distinction between humans and other apes must lie somewhere in the small genetic differences between the species," says McLysaght.
One challenge is to connect measurements of natural selection on phenotypic traits to genetic changes underlying evolved differences between the species.
This argument considers only the fate of hybrids, but in fact not many hybrids are formed because of behavioral differences between the species.
Population differences in size and shape persist when fish are raised in the lab, which means that differences between the species are genetically based rather than environmentally induced.
Even before the sequencing of the chimp and human genomes, geneticists suspected that changes in gene activity underlie differences between the species.
