Specimens of Archaeopteryx colouration and patterning of the plumage cannot be drawn with certainty from this study. In 2011, graduate student Ryan Carney and colleagues performed the first colour study on an "Archaeopteryx" specimen with the fossil of this single feather. Using scanning electron microscopy technology and energy-dispersive X-ray analysis, the team was able to detect the structure of melanosomes in the fossil. The resultant structure was then compared to that of 87 modern bird species and was determined with a high percentage of likelihood to be black in colour. While the study does not mean that "Archaeopteryx" was entirely black, it does
Ancestor yet the number 2, approximately 10 or one trillion, dwarfs the number of humans who have ever lived. Some cultures confer reverence to ancestors, both living and dead; in contrast, some more youth-oriented cultural contexts display less veneration of elders. In other cultural contexts, some people seek providence from their deceased ancestors; this practice is sometimes known as "ancestor worship" or, more accurately, "ancestor veneration".
