The quagga (/ ˈ k w ɑː x ɑː / or / ˈ k w æ ɡ ə /) [2] [3] (Equus quagga quagga) is an extinct subspecies of the plains zebra that was endemic to South Africa until it was hunted to extinction in the late 19th century. It was long thought to be a distinct species, but MtDNA studies have supported it being a subspecies of plains zebra.
The plains zebra (Equus quagga, formerly Equus burchellii) is the most common and geographically widespread species of zebra. Its range is fragmented, but spans much of southern and eastern Africa south of the Sahara. Six or seven subspecies have been recognised, including the quagga which was thought to be a
Molecular paleontology techniques applied to fossils have contributed to the discovery and characterization of several new species, including the Denisovans and Homo heidelbergensis. We have been able to better understand the path that humans took as they populated the earth, and what species were present during this diaspora .
Quagga (Equus quagga quagga), an extinct sub-species of zebra. The first study of what would come to be called aDNA was conducted in 1984, when Russ Higuchi and colleagues at the University of California, Berkeley reported that traces of DNA from a museum specimen of the Quagga not only remained in the specimen over 150 years after the death of the individual, but could be extracted and ...
Paleogenetics is the study of the past through the examination of preserved genetic material from the remains of ancient organisms. [1] [2] Emile Zuckerkandl and Linus Pauling introduced the term in 1963, long before the sequencing of DNA, in reference to the possible reconstruction of the corresponding polypeptide sequences of past organisms.

In archaeology and paleontology a faunal assemblage is a group of animal fossils found together in a given stratum. [1] In a non-deformed deposition, fossils are organized by stratum following the laws of uniformitarianism [2] and superposition, [3] which state that the natural phenomena observable today (such as death, decay, or post-mortem transport) also apply to the paleontological record ...
The fossils were first uncovered during the school’s modernization project, which began in 2022. The first find was unearthed in June 2022 beneath the school’s main courtyard, ...
In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials.
