I would like to see the peer-reviewed version of this story.

Go to: Monogamy gene found in people

Gunnar's Avatar Jump to comment 22 by Gunnar

This headline is misleading and oversimplificating; a good example of what is wrong with journalism in general and science journalism in particular today. The RS3 334 gene seems to have a behavioural effect on men, and is such LINKED to monogamy. Saying that it is "the" monogamy gene is nonsense.

It is also wrong saying that having many copies of the RS3 334 gene automatically makes someone bad at relationships. Behavioural genetics is not a story about genetic determinism, but of genetic probalism - genetic differences does make a given behavioural trait more likely to happen in some individuals than others, but it is still not a safe bet.

Go to: Trichoplax Genome Sequenced: 'Rosetta Stone' For Understanding Evolution

Gunnar's Avatar Jump to comment 17 by Gunnar

I understood from the article that 80% of Trichoplax' genes are also found in humans. This does not imply that the human and the Trichoplax genome are 80% alike; the mathemathics are given quite correctly above by Angels on a Pin Head.

According to Brusca & Brusca's zoology textbook Invertebrates; Trichoplax adhaerens are basically 0,5-3 mm wide lumps of a few thousand cells. They spend their time crawling around using their cilia (like amoeba and some flatworms); grazing on algae for the most part in sandy marine areas all over the tropical world. Their inner "organs" are merely amoeboid cells (cellular multi-taskers) in a liquid-filled mesenchyme medium.

They are interesting because they represent a basal line in the evolution of multicellular animals; as far as I know it is not clear whether they are closer to the eumetazoa than the sponges. Their genome surely will throw some light over the overall evolution of multicellular animals.

I hope a sponge genome will be sequenced soon!

Go to: Mecca should become core to measure time zones: scholars

Gunnar's Avatar Jump to comment 71 by Gunnar

I don't see any reason why the zero meridian could not be moved to Mecca. If a majority of the world's inhabitants wish for it to be so, why should we keep GWT from becoming MWT?

The placement of the zero meridian is a matter of habit, not scientific fact.
