These unusual and beautiful trees were once exported from New
Caledonia (an archipelago in the southwest Pacific) and
thanks to its ornamental spread throughout the world. how
it turned out they have one very strange property to which
before people did not pay attention.
Today, Cook’s Pines, named after them
discoverer, grow on five continents. However wherever
this tree was located, it invariably grows under a certain inclination.
Least of all is the slope of the pines that grow in their homeland –
in New Caledonia. He really is so small that no one noticed
him, until Cook’s pine trees spread across our planet.
The oddity of the Cook pines, discovered by Matt Ritter
The first to notice this striking feature was the American
botanist matt ritter (california polytechnic state
university). It happened like this. Ritter called his
to an Australian colleague to share a curious observation: everything
Cook’s pines are tilted tops to the south. how же он удивился, когда в

scientists, the more they were amazed. It turned out that the slope of the trees
depends not only on the hemisphere in which the pines grew, but also on

Researchers have put forward several versions that can explain
Cook’s pines feel the earth’s geomagnetic field?
According to the first theory, the unnatural slope of a tree is
the result of mutations in the mechanism of development of the trunk. However this
the hypothesis does not explain why the slope depends on the hemisphere, and
Version two. Some plants are known to

Does Cook have any similar mechanism? But then what is
the purpose of the slope of its trunk?
And the last hypothesis, according to which Cook pines feel

But even if we accept this theory, the question remains: why do trees
