Penghu 1
Penghu 1 is a fossil jaw (mandible) belonging to an extinct hominin species of the genus ''Homo'' from Taiwan which lived in the middle-late Pleistocene. The precise classification of the mandible is disputed, some arguing that it represents a new species, ''Homo tsaichangensis'', whereas others believe it to be the fossil of a ''H. erectus'', an archaic '' H. sapiens'' or possibly a Denisovan. History and discovery The fossil was recovered sometime before 2008 by fishermen working in the Pescadores Channel between the Penghu Islands and mainland Taiwan. It was found 60–120 meters below the water's surface and about 25 kilometers off the western coast of Taiwan in an area which was once part of the mainland. Sea levels have risen since the last ice age and in consequence have submerged the area where the fossil was recovered. It was described in 2015 by an international team of Japanese, Taiwanese, and Australian scientists. Penghu 1 is currently housed at the National Museum ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

3D Reconstruction
In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. If the model is allowed to change its shape in time, this is referred to as spatio-temporal reconstruction, non-rigid or spatio-temporal reconstruction. Motivation and applications The research of 3D reconstruction has always been a difficult goal. By Using 3D reconstruction one can determine any object's 3D profile, as well as knowing the 3D coordinate of any point on the profile. The 3D reconstruction of objects is a generally scientific problem and core technology of a wide variety of fields, such as Computer Aided Geometric Design (CAGD), computer graphics, computer animation, computer vision, medical imaging, computational science, virtual reality, digital media, etc. For instance, the lesion information of the patients can be presented in 3D on the computer, which offers a new ...

Tibetan Plateau
The Tibetan Plateau (, also known as the Qinghai–Tibet Plateau or the Qing–Zang Plateau () or as the Himalayan Plateau in India, is a vast elevated plateau located at the intersection of Central, South and East Asia covering most of the Tibet Autonomous Region, most of Qinghai, western half of Sichuan, Southern Gansu provinces in Western China, southern Xinjiang, Bhutan, the Indian regions of Ladakh and Lahaul and Spiti (Himachal Pradesh) as well as Gilgit-Baltistan in Pakistan, northwestern Nepal, eastern Tajikistan and southern Kyrgyzstan. It stretches approximately north to south and east to west. It is the world's highest and largest plateau above sea level, with an area of (about five times the size of Metropolitan France).

Xiahe Mandible
The Xiahe mandible (, ) is a hominin fossil jaw (mandible) discovered in Baishiya Karst Cave, located on the northeastern edge of the Tibetan Plateau in Xiahe County, Gansu, China. By the use of palaeoproteomic analysis, it is the first confirmed discovery of a Denisovan fossil outside of Denisova Cave, and the most complete confirmed Denisovan fossil. This fossil discovery shows that archaic hominins were present in a high-altitude, low-oxygen environment around 160,000 years ago. ''Discover'', '' Science News'' and ''Nova'' all named the discovery of the mandible in their lists of Top Science Stories of 2019. History The Xiahe mandible was discovered in 1980 in the Baishiya Karst Cave, located on the northeastern edge of the Tibetan Plateau in Xiahe County, Gansu, China. It was found by a Tibetan Buddhist monk who was meditating in the cave. He passed the bone to , the sixth tulku, who recognized it as an important hominin fossil and gave it to geologist Dong Guangrong o ...

Archaic Humans
A number of varieties of ''Homo'' are grouped into the broad category of archaic humans in the period that precedes and is contemporary to the emergence of the earliest early modern humans (''Homo sapiens'') around 300 ka. Omo-Kibish I (Omo I) from southern Ethiopia ( 195 or 233 ka), the remains from Jebel Irhoud in Morocco (about 315 ka) and Florisbad in South Africa (259 ka) are among the earliest remains of ''Homo sapiens''. The term typically includes ''Homo neanderthalensis'' (430 ± 25 ka), Denisovans, ''Homo rhodesiensis'' (300–125 ka), ''Homo heidelbergensis'' (600–200 ka), ''Homo naledi'', ''Homo ergaster'', ''Homo antecessor'', and '' Homo habilis''. There is no universal consensus on this terminology, and varieties of "archaic humans" are included under the binomial name of either ''Homo sapiens'' or ''Homo erectus'' by some authors. Archaic humans had a brain size averaging 1,200 to 1,400 cubic centimeters, which overlaps with the range of modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pongidae
Pongidae , or the pongids is an obsolete primate taxon containing chimpanzees, gorillas and orangutans. By this definition pongids were also called "great apes". This taxon is not used today but is of historical significance. The great apes are currently classified as Hominidae. This entry addresses the old usage of pongid. The words "Pongidae" and "pongids" are sometimes used informally for the primate taxon containing orangutans and their extinct fossil relations. For this usage the currently most widely accepted name is Ponginae (or informally Asian hominids or pongines), the orangutan subfamily of the Hominidae or hominids. In current hominid taxonomy there is no “pongid” taxon. The orangutan taxon is now known to be paraphyletic to other (African) hominids. The orangutans are the only surviving species of the subfamily Ponginae, which genetically diverged from the other hominids (gorillas, chimpanzees and humans) between 19.3 and 15.7 million years ago. The subfamilies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy. The recurrent evolution of flight is a classic example, as flying insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas '' homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different traits. Convergent evolution is similar to parallel evo ...
