To study how ecological factors, especially diets, impact the evolution of the umami taste, we examined the umami taste receptor gene Tas1r1 in a phylogenetically diverse group of bats including fruit eaters, insect eaters, and blood feeders.
It is always useful to have a large exhibition that gives a sense of the evolution of subject, taste and style in American art.
Furthermore, we found that carnivorous birds carry a smaller Tas2r repertoire than do other birds and observed a positive correlation between the number of putatively functional Tas2rs and the amount of potential toxins in the diet, supporting the hypothesis that dietary toxins have driven the evolution of bitter taste receptor genes, even in bird species carrying diminutive Tas2r repertoires.
In addition to diet selection, however, extraoral functions (e.g., in gastrointestinal tract or respiratory epithelium) (Wu et al. 2002; Finger et al. 2003) may also drive the evolution of bitter taste receptor genes in birds, a hypothesis that awaits future investigation.
And the Mugas are as canny at business as they are good at making wine: They saw the evolution of public tastes in the 1980s and, while they never gave up on gran reservas, they set out to make a more powerful wine, aged in new barrels of French oak, with more prominent fruit flavors that required less aging before hitting the market.
In this study, we surveyed all five primary taste receptor genes in toothed and baleen whales to examine the generality of whale taste loss and test whether taste loss has influenced the evolution of taste signal transduction.
The British Museum has reconsidered its display of the Elgin Marbles several times over the years, and the evolution of taste illustrated by these alterations is itself of cultural interest.
To test whether widespread losses of taste receptor genes have affected the evolution of taste signaling pathways, we examined three genes (Calhm1, Trpm5, and Plcβ2) that are known to be involved in taste signaling (Zhang et al. 2003; Taruno et al. 2013).
It is such a personal thing for the Baileys - an evolution of their taste over two decades - that they don't feel the need to analyse it.
It is inconceivable that decisions of such emotional intimacy and magnitude were not made with an eye toward the character of the prospective mate, and that these decisions did not therefore figure in the evolution of the human personality with its tastes, values and interests.
