Aspen

Species[edit] These species are called aspens: Populus adenopoda: Chinese aspen (China, south of P. tremula)Populus grandidentata: Bigtooth aspen (eastern North America, south of P. tremuloides)Populus sieboldii: Japanese aspen (Japan)[citation needed]Populus tremula: Eurasian aspen (northern Europe and Asia)Populus tremuloides: Quaking aspen (northern and western North America) Crocodile. Etymology The word "crocodile" comes from the Ancient Greek κροκόδιλος (crocodilos), "lizard," used in the phrase ho krokódilos tou potamoú, "the lizard of the (Nile) river".

Crocodile

There are several variant Greek forms of the word attested, including the later form κροκόδειλος (crocodeilos)[4] found cited in many English reference works.[5] In the Koine Greek of Roman times, crocodilos and crocodeilos would have been pronounced identically, and either or both may be the source of the Latinized form crocodīlus used by the ancient Romans. Crocodilos or crocodeilos is a compound of krokè ("pebbles"), and drilos/dreilos ("worm"), although drilos is only attested as a colloquial term for "penis".[5] It is ascribed to Herodotus, and supposedly describes the basking habits of the Egyptian crocodile.[6] Species Distribution of crocodiles.

Poachers Are Killing Thousands of African Vultures to Hide Evidence of Their Crimes. Ending "Shamu" stunts isn't enough to protect whales, activists say. SAN DIEGO, Calif. — Animal rights activists applauded SeaWorld's plans to end its orca shows in San Diego.

However, they said the marine park should stop keeping killer whales in captivity altogether. SeaWorld Entertainment Inc. made the announcement Monday about ending the shows. Visitors at the San Diego park made it clear they prefer seeing killer whales act naturally rather than doing tricks. The famous "Shamu" show began at the San Diego park many years ago.

It featured killer whales doing flips and other stunts. Frozen Scythian stallions unravel mysteries of horse domestication. First tamed by humans about 6000 years ago, horses today bear distinct marks of their early domestication.

Frozen Scythian stallions unravel mysteries of horse domestication

Thousands of years of inbreeding, for example, have littered horse genomes with detrimental DNA. And because modern stallions all share a similar Y chromosome, early equestrians must have studded their herds with just a few males. Or so researchers thought. Now, by sequencing the genomes of 11 frozen stallions buried 2300 years ago in a Scythian prince’s tomb in the permafrost of Kazakhstan (above), researchers have discovered that the first horses came from plentiful male stock. Especial: Darwin en Argentina. Enslaved worker ants fight back through acts of sabotage. What's particularly fascinating about this discovery is that the enslaved ants are not the ones passing the "destroy enemy pupae" genes to the next generation.

Instead, this characteristic is arising and being reenforced among the free ants. [Puts on evolutionary biologist wizard's hat] Ahem. While learned behavior is certainly possible, I wouldn't completely exclude genetic causes, or at least a genetic predisposition towards this behavior. When talking about genetics and evolutionary adaptation, it is vitally important to understand that all evolution cares about is the survival of genes rather than the survival of individual organism.
