Sentences with phrase «genes with chimpanzees»

One very stupid question I have, which I hope you don't mind my asking: If I share 70 % of my genes with sea sponges, and 98 % of my genes with chimpanzees, and genes are the unit of selection, why doesn't Hamilton's rule say that I'd be willing to sacrifice myself for 1.02 chimpanzees or 1.43 sea sponges?

We may share many genes with chimpanzees, but it's rare for them to cluster together in the same combinations.

Not exact matches

In particular, humans share an unfortunate «broken gene» with many other primates, including chimpanzees, orangutans, and macaques.

She picked those non-human primates because they are the closest relatives in the animal kingdom, especially gorillas and chimpanzees, who share more than 98 % of their genes with humans.

The team found that humans are equipped with tiny differences in a particular regulator of gene activity, dubbed HARE5, that when introduced into a mouse embryo, led to a 12 % bigger brain than in the embryos treated with the HARE5 sequence from chimpanzees.

«We found that chimpanzees, orangutans and gorillas do not show a significant overlap of genes under positive selection with domesticates.

He says this idea has «very profound» implications for the debate over the origins of bacterial genes that are present in the human genome but absent in our closest relatives (Science, 8 June, p. 1903): The amount of conjugation Waters detected is «high enough to readily explain» the possible infiltration of bacterial genesinto our DNA, meaning that conjugation could have happened quickly enough to add genes only to humans, in the years since they split from the common ancestor they shared with chimpanzees.

Before this study, scientists debated how these immune genes can evolve rapidly (which is necessary to keep up with the fast - evolving parasites), whilst also showing little or no evolutionary change in their function over millions of years, as observed between humans and chimpanzees.

But if the genes for handedness evolved with humans, why are so many chimpanzees left - handed and in such predictable numbers?

When Peter Parham's postdoc first showed him data suggesting a gene in some wild chimpanzees infected with the AIDS virus closely resembled one that protects humans from HIV, he was skeptical.

The team found that ARHGAP11B was also present in Neanderthals and Denisovans, human cousins with similarly sized brains, but not in chimpanzees, with which we share 99 percent of our genome — further support for the idea that this gene could explain our unusually large human brains.

Svante Pääbo Last year Pääbo announced a plan to sequence the entire Neanderthal genome by 2008 and compare our extinct relative's genes with the genes of chimpanzees and humans.

Comparisons with the chimpanzee genome indicate that human SIGLEC11 emerged through human - specific gene conversion by an adjacent pseudogene.

To assess the speed with which both humans and chimpanzees accumulated many small differences in gene sequences accurately, Wu and colleagues in Taiwan and Japan decided to sequence several thousand genes expressed in the brain of the macaque monkey and compare them with available genomic sequences from human, chimpanzee, and mice.
