  ColeochaetophyceaeColeochaetophyceae is a class of charophyte algae related to land plants, and is estimate to be 606.1 ± 119.4 million years old. There are about 35 known species, and are predominantly found in freshwater where they live periphytic on the surface of aquatic plants, plastic bags and pebbles in the shallow littoral zone of freshwater lakes. These are small disc-shaped or filamentous species – the filaments can be spread radially or be irregularly branched – but can reach several millimeters in diameter, and have true multicellular organisation with sexual and asexual reproduction. The discs never develop beyond a two-dimensional organization. Their mitogenome is the most intron rich organelle among the streptophyte algae. The sperm cells are flagellated, but the egg has no flagella, and the following zygote pssesses algaenan, which sporopollenin. The group contain two orders, Coleochaetales and Chaetosphaeridiales.

  Behavioral modernityBehavioral modernity is a suite of behavioral and cognitive traits associated with humans, reflecting capacities such as abstract and symbolic thought, planning depth, cumulative culture, and complex social learning. These traits are often inferred archaeologically through evidence including symbolic artifacts, ritualized behavior, music and dance, sophisticated hunting strategies, and advanced lithic technologies such as blade production. Rather than representing an absolute boundary between Homo sapiens and other hominins, behavioral modernity is increasingly understood as a mosaic of traits that emerged gradually and were expressed variably across time and populations.

  Dance in the United StatesThe United States of America is the home of the hip hop dance, swing, tap dance and its derivative Rock and Roll, and modern square dance and one of the major centers for modern dance. There is a variety of social dance and performance or concert dance forms with also a range of traditions of Native American dances. The reality shows and competitions So You Think You Can Dance, America's Best Dance Crew, and Dancing with the Stars, have broadened the audience for dance.

  Fire PhoneThe Fire Phone is a discontinued 3D-enabled smartphone developed by Amazon and manufactured by Foxconn. It was announced on June 18, 2014, and marked Amazon's first foray into the smartphone market, following the success of the Kindle Fire. It was available for pre-order on the day it was announced. In the United States, it launched as an AT&T exclusive on July 25. Notable for its hallmark feature "Dynamic Perspective" using five front-facing cameras and the gyroscope to track the user's movements, the phone's Fire OS adjusts the UI so it gives the impression of depth and 3D. Other notable Amazon services on the phone include X-Ray, used for identifying and finding information about media; Mayday, the 24-hour customer service tool; and Firefly, a tool for automatically recognizing text, sounds, and objects, and offering a way to buy recognized items through Amazon's online store. The phone received mixed reviews. Critics praised the Dynamic Perspective, Firefly and, to a lesser extent, the packaged headphones, but derided the build, design, Fire OS version of Android, specifications, and exclusivity to AT&T. Amazon does not release sales figures for any of its devices, but based in part on its quickly declining prices and an announced US$170 million write-down, analysts have judged it a commercial failure. Amazon ceased production of the Fire Phone in August 2015 and discontinued sales soon after.
