Given that the brain is among the most plastic organs in general, the results emphasize the view that common garden data are required to draw firm evolutionary conclusions from patterns of brain size variability in the wild.
Another review considers the general difficulties of reaching firm evolutionary conclusions about the evolutionary significance of recessive alleles and the excessive attention associated with hypotheses about heterozygote advantage (Valles 2010).
UC provided the microarray experimental facility and revised the manuscript critically for the content of evolutionary conclusions.
Our results indicate that model choice can lead to fundamentally different evolutionary conclusions, emphasizing the importance of more biologically realistic and complex models.
Today, through over a century of study of both the Earth's surface and the completeness of the fossil record, paleontologists have been able to determine that while the record will never be complete and always has preservation biases, we often have more than enough evidence to draw strong evolutionary conclusions about the history of many groups, both living and extinct.
The results emphasize the importance of taking a comprehensive and rigorous approach to questions of presence/absence of genes/organelles before drawing firm evolutionary conclusions.
The comparative studies that have been the building blocks of these important evolutionary conclusions have been greatly assisted by many newly discovered Mesozoic-aged birds (Chiappe 2007), which by possessing many skeletal features that are only slightly modified from the ancestral maniraptoran condition, fill a critical gap in the evolutionary transition toward modern birds (Figs. 1, 4, and 5).
In conclusion, we have demonstrated unexpected diversity and evolutionary dynamics of the bacterial symbionts in feather lice of the genus Columbicola.
In conclusion, using a combination of bioinformatics and experimental approaches, we have delineated structural and evolutionary trends of TRs in euchromatic regions.
