This long, well-documented period of contact provides some of the best linguistic evidence for contact-induced grammatical change. That is to say, Spanish seems to have exerted a profound influence on the Nahuatl language, but despite the extreme duration of their contact Nahuatl has only recently begun to show signs of language shift.
Homo antecessor (Latin "pioneer man") is an extinct species of archaic human recorded in the Spanish Sierra de Atapuerca, a productive archaeological site, from 1.2 to 0.8 million years ago during the Early Pleistocene. Populations of this species may have been present elsewhere in Western Europe, and were among the first to settle that region ...
The evidence of pax-6, however, was that the same genes controlled the development of the eyes of all these animals, suggesting that they all evolved from a common ancestor. [9] Ancient genes had been conserved through millions of years of evolution to create dissimilar structures for similar functions, demonstrating deep homology between ...
This word ending—thought to be difficult for Spanish speakers to pronounce at the time—evolved in Spanish into a "-te" ending (e.g. axolotl = ajolote). As a rule of thumb, a Spanish word for an animal, plant, food or home appliance widely used in Mexico and ending in "-te" is highly likely to have a Nahuatl origin.
The highly diverse Nilo-Saharan languages, first proposed as a family by Joseph Greenberg in 1963 might have originated in the Upper Paleolithic. [1] Given the presence of a tripartite number system in modern Nilo-Saharan languages, linguist N.A. Blench inferred a noun classifier in the proto-language, distributed based on water courses in the Sahara during the "wet period" of the Neolithic ...
Evidence of common descent – Common ancestor evolutionary evidence; Evolutionary grade – Non-monophyletic grouping of organisms united by morphological or physiological characteristics; Lineage (evolution) – Sequence of populations, organisms, cells, or genes that form a line of descent
This has consequences for our understanding of: (i) the origins of the E and L components found in bird and monkey communication systems; (ii) the rapid emergence of human language as related to words; (iii) evidence of hierarchical structure within compound words; (iv) the role of phrases in the detection of the structure building operation ...
Orthogenesis, also known as orthogenetic evolution, progressive evolution, evolutionary progress, or progressionism, is an obsolete biological hypothesis that organisms have an innate tendency to evolve in a definite direction towards some goal (teleology) due to some internal mechanism or "driving force".
