The teams report that humans do not possess many more genes than other, less complex, organisms.
The work suggests that many more genes than had been assumed are regulated by the clock.
Since then genetic analyses have revealed many more genes involved in this process.
The mouse, for instance, to serve its acuter sense of smell, has developed many more genes related to odor detection than people have.
The main mystery is how to explain human complexity when we do not have all that many more genes than a worm.
The Mongols, because of their rulers' harems, left behind many more genes than conquering armies usually do, but their language vanished from their conquered territories.
Drayna said many more genes could be implicated in causing stuttering, but a better understanding of the biological basis of stuttering could help in the production of treatments.
Both teams devote part of their huge articles to discussing how it is that humans are more complicated than simple invertebrate animals even though they possess not that many more genes.
This explains why the plant has so many more genes than types of protein (many of its proteins are similar, belonging to families turned out by duplicated genes).
Many more genes remain uncharacterized, especially for the non-syndromic XLMR forms.
However, it is still unclear how many more genes are implicated in this process, and methods are needed to systematically evaluate each gene's relevance to reprogramming.
