The name was usually explained by the ancients as meaning 'the city of Janus' (Serv. Aen. VIII.357; Varro ap. August. civ. Dei VII.4; Solin. II.5; Macrob. I.7.19; Ov. Fast. I.245); sometimes, apparently, as the 'gate' (Fest. 104).
If LunaH-Map's observed distributions of polar ices and water-rich compounds match models of the Moon's ancient polar wander, then it's likely that their current distribution can be explained by the Moon's ancient wobbles, says Hardgrove.
This could be explained by the extensive and ancient polyploidization (palaeopolyploidy) of the order (Chiarugi 1960).
The 13% of the Arabidopsis genome covered in depth 4, and total of 20% covered in depths > = 4, are shown below to be partly explained by the 'shadows' of more ancient genome duplications.
Sparta's ancient dual kingship was explained by the founding legend, that the original conquerors of Sparta were twin brothers and their descendants shared Sparta.
The idea that some characteristics of an organism are explained by the organism's intrinsic nature, whilst others reflect the influence of the environment is an ancient one.
Whilst we cannot discount an ancient origin for GLDH in the last common eukaryote ancestor, its distribution may also be reasonably explained by the lateral gene transfer model.
For example, the strong southern hemispherical preference of the crustal magnetisation can be explained by an ancient dynamo that operated more efficiently in the southern hemisphere.
In the case of X. clemenciae, the discrepancy in the phylogenetic position was parsimoniously explained by an ancient hybridization event between a swordless platyfish, such as X. maculatus (or X. milleri), as the maternal species, and a sworded southern swordtail as the paternal species, such as X. hellerii in the previous studies [ 11, 22, 58].
The existence of multiple lysozyme g genes in diverse vertebrate species can be explained by either ancient gene duplications generating multiple genes in the common ancestor of vertebrates or parallel recent duplications of lysozyme g genes in diverse lineages.
