Such facilitation could be particularly significant in the case of rapid evolutionary changes such as the emergence of Homo sapiens.
As such, they present an attractive outgroup from which to investigate how evolutionary changes in the genetic toolkit may have contributed to the emergence of the complex animal body plans of the Bilateria.
As a result, the hagfish "eye" may provide a window into an evolutionary step in the emergence of our own eye.
The GUH-2 genomic sequence was also used to identify key evolutionary events in the emergence of N. cyriacigeorgica.
This observation raises intriguing questions about the origin of tuberculosis and provided an opportunity to examine the molecular and evolutionary events involved in the emergence of M. tuberculosis.
Observations that FOXP2 orthologues show almost no variation across distantly related species of reptile, bird and mammal [3] [5], while the gene differs by two adaptive amino acid changes between humans and chimpanzees [3], [5], has led to speculation that recent evolutionary changes in FOXP2 might be related to the emergence of language [3], [5], [6].
"What we have now is an evolutionary pathway for the emergence of monogamy".
An accumulation of discoveries has revealed many of the evolutionary steps leading to the emergence of humans in Africa more than 100,000 years ago.
In consequence, there would have been strong evolutionary driving forces for the emergence of the xeroxase/replicase, a polymerase capable of acting on itself and/or another template.
In seeking for a scientific explanation one has to search for step-by-step evolutionary changes from prebiotic chemistry to the emergence of the first proto-cell.
This cohabitation, along with undisputed benefits, has created an evolutionary conundrum, closely involved in the emergence of infectious diseases.
