Symmetry equals sex Starting at conception, the human body develops by neatly splitting cells.
If every division were to go perfectly, the result would be a baby whose left and right sides are mirror images. Genetic mutations and environmental pressures skew symmetry, and the results have lifelong implications.
Pecking, smooching, French kissing, and playing tonsil-hockey — there are as many names for kissing as there are ways to do it.
Whether we use it as an informal greeting or an intensely romantic gesture, kissing is one of those ingrained human behaviors that seems to defy explanation.
More than 12,500 of an estimated total of 22,000 species have been classified.
They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.
How it all factors into true love is even more mysterious.
One of the best things about kissing, however, is that we don’t have to think about any of this.
Ants have colonised almost every landmass on Earth.
The only places lacking indigenous ants are Antarctica and a few remote or inhospitable islands.
Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals.
Larger colonies consist mostly of sterile, wingless females forming castes of "workers", "soldiers", or other specialised groups.
