Oldest Viable Seed
There have been several seeds known at different times as the oldest viable seed. Dormancy allows seeds to survive for extended periods, which can aid in seed dispersal and spread out the growth and establishment of seedlings, increasing the likelihood that some of the next generations survive if conditions are not suitable for seedling establishment. Over time, seeds lose viability, which is the ability to initiate metabolic activity, cellular growth, and germination. Seeds have many cells and tissues that die over time, and these deaths can be delayed or increased by environmental conditions the seed experiences. Very generally, small seeds, especially from weedy species and annuals are more likely to remain viable in the soil longer than larger perennial seeds. The seeds of some aquatic plants also may remain viable longer in mud because their viability is aided by the aquatic environment which remains cool and moist.

Silene Stenophylla 115390032
''Silene'' is a genus of flowering plants in the family Caryophyllaceae. Containing nearly 900 species, it is the largest genus in the family. Common names include campion and catchfly. Many ''Silene'' species are widely distributed, particularly in the northern hemisphere. Scientific history Members of this genus have been the subject of research by preeminent plant ecologists, evolutionary biologists, and geneticists, including Charles Darwin, Gregor Mendel, Carl Correns, Herbert G. Baker, and Janis Antonovics. Many ''Silene'' species continue to be widely used to study systems, particularly in the fields of ecology and evolutionary biology.Bernasconi et al. 2009. Silene as a model system in ecology and evolution. Heredity. 103:5-14. PMI19367316/ref> The genus has been used as a model for understanding the genetics of sex determination for over a century. ''Silene'' species commonly contain a mixture of hermaphroditic and female (or male-sterile) individuals (gynodioecy), an ...

The Judean date palm is a date palm (''Phoenix dactylifera'') grown in Judea. It is not clear whether there was ever a single distinct Judean cultivar, but dates grown in the region have had distinctive reputations for thousands of years, and the date palm was anciently regarded as a symbol of the region and its fertility. Cultivation of dates in the region almost disappeared after the 14th century AD from a combination of climate change and infrastructure decay but has been revived in modern times. In 2005, a team of scientists sprouted a preserved 2,000-year-old seed, the oldest seed germinated with human-assistance (with the claim in 2012 of a 32,000-year-old arctic flower involving fruit tissue rather than a seed). The palm, a male, was named Methuselah (not to be confused with a bristlecone pine tree of the same name). Following this success, six further preserved seeds were sprouted. History Fruit of the date palm was considered a staple food in the Judaean Desert, as it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient Egypt In The Western Imagination
upright=1.1, The Nile Mosaic of Palestrina. The culture of Ancient Egypt has fascinated outsiders from its own day well into our own, long after that culture was subsumed first by Greco-Roman, then Christian, then Muslim currents. And while the concept of the "Western world" owes its origin to Christian writers of early medieval Europe and Asia Minor, those same writers were keen to imagine themselves as part of—or heirs to—a cultural continuum that began with classical antiquity and evolved to include the Biblical history of the Jews. In Western cultures' collective imaginings, the idea of "Ancient Egypt" has developed and changed over millennia no less than those cultures themselves changed. From classical and late antiquity through the Middle Ages, the Renaissance, the Enlightenment, and into the modern era, this imagined "Egypt" has served as a powerful symbol, variously representing profound antiquity, esoteric wisdom, evil, the exotic, or timeless grandeur.

Ancient Egypt
Ancient Egypt () was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were amalgamated by Menes, who is believed by the majority of List of Egyptologists, Egyptologists to have been the same person as Narmer. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by the "Periodization of ancient Egypt, Intermediate Periods" of relative instability. These stable kingdoms existed in one of three periods: the Old Kingdom of Egypt, Old Kingdom of the Early Bronze Age; the Middle Kingdom of Egypt, Middle Kingdom of the Middle Bronze Age; or the New Kingdom of Egypt, New Kingdom of the Late Bronze Age. The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt ...

Yukon Territory
Yukon () is a territory of Canada, bordering British Columbia to the south, the Northwest Territories to the east, the Beaufort Sea to the north, and the U.S. state of Alaska to the west. It is Canada’s westernmost territory and the smallest territory by land area. As of the 2021 census, Yukon is the middle territory in terms of population, but the most densely populated. Yukon has an estimated population of 47,126 as of 2025. Whitehorse, the territorial capital, is the largest settlement. Yukon was split from the Northwest Territories by a federal statute in 1898 as the Yukon Territory. The current governing legislation is a new statute passed by the federal Parliament in 2002, the ''Yukon Act''. That act established Yukon as the territory's official name, although Yukon Territory remains in popular usage. Canada Post uses the territory's internationally approved postal abbreviation of YT. In 2021, territorial government policy was changed so that The Yukon would be rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
