subrealism: the biological origin of linguistic diversity

subrealism: the biological origin of linguistic diversity | manually by oAnth - from its scoop.it contacts | Scoop.it
Just as reading relies on neural mechanisms that pre-date the emergence of writing [17], so perhaps language has evolved to rely on pre-existing brain systems. However, there is more agreement about the origin of linguistic ...

(Abstract) In contrast with animal communication systems, diversity is characteristic of almost every aspect of human language. Languages variously employ tones, clicks, or manual signs to signal differences in meaning; some languages lack the noun-verb distinction (e.g., Straits Salish), whereas others have a proliferation of fine-grained syntactic categories (e.g., Tzeltal); and some languages do without morphology (e.g., Mandarin), while others pack a whole sentence into a single word (e.g., Cayuga). A challenge for evolutionary biology is to reconcile the diversity of languages with the high degree of biological uniformity of their speakers. Here, we model processes of language change and geographical dispersion and find a consistent pressure for flexible learning, irrespective of the language being spoken. This pressure arises because flexible learners can best cope with the observed high rates of linguistic change associated with divergent cultural evolution following human migration. Thus, rather than genetic adaptations for specific aspects of language, such as recursion, the coevolution of genes and fast-changing linguistic structure provides the biological basis for linguistic diversity. Only biological adaptations for flexible learning combined with cultural evolution can explain how each child has the potential to learn any human language.

On the border between matter and anti-matter: Nanoscientists find long-sought Majorana particle

Scientists in the Netherlands have succeeded for the first time in detecting a Majorana particle.

Quantum computer and dark matter

 

Majorana fermions are very interesting -- not only because their discovery opens up a new and uncharted chapter of fundamental physics; they may also play a role in cosmology. A proposed theory assumes that the mysterious 'dark matter', which forms the greatest part of the universe, is composed of Majorana fermions. Furthermore, scientists view the particles as fundamental building blocks for the quantum computer. Such a computer is far more powerful than the best supercomputer, but only exists in theory so far. Contrary to an 'ordinary' quantum computer, a quantum computer based on Majorana fermions is exceptionally stable and barely sensitive to external influences.

"The change in society brought about by the teaching of modern arithmetic was so pervasive and all-powerful that within a few generations people simply took it for granted. There was no longer any recognition of the magnitude of the revolution that took the subject from an obscure object of scholarly interest to an everyday mental tool. Compared with Copernicus’s conclusions about the position of Earth in the solar system and Galileo’s discovery of the pendulum as a basis for telling time, Leonardo’s showing people how to multiply 193 by 27 simply lacks drama.” ~ Keith Devlin

World-first hybrid shark found off Australia | uk.news.yahoo.com

World-first hybrid shark found off Australia | uk.news.yahoo.com | manually by oAnth - from its scoop.it contacts | Scoop.it
Scientists said on Tuesday that they had discovered the world's first hybrid sharks in Australian waters, a potential sign the predators were adapting to cope with climate change.

 

--------------------------------------

 

// quotation by oAnth:

 

[...]

 

The Australian black-tip is slightly smaller than its common cousin and can only live in tropical waters, but its hybrid offspring have been found 2,000 kilometres down the coast, in cooler seas.

 

It means the Australian black-tip could be adapting to ensure its survival as sea temperatures change because of global warming.

 

"If it hybridises with the common species it can effectively shift its range further south into cooler waters, so the effect of this hybridising is a range expansion," Morgan said.

"It's enabled a species restricted to the tropics to move into temperate waters."

 

Climate change and human fishing are some of the potential triggers being investigated by the team, with further genetic mapping also planned to examine whether it was an ancient process just discovered or a more recent phenomenon.

Posons la question grossièrement : pourquoi la
science est-elle née en Europe, pourquoi à cette époque, et non au sein
d’une autre civilisation et/ou à une autre époque ? Y a-t-il une
explication, ou est-ce seulement un fait contingent qui aurait pu ne pas se
produire, la culture indienne ou chinoise donnant lieu à la physique
mathématique, ou encore la culture musulmane, qui disposa avant la
culture chrétienne des mêmes bases théoriques de la philosophie
naturelle ?
Cette question renvoie à la thèse de l’engendrement de la science
moderne par la culture médiévale, défendue par Pierre Duhem dans ses
ouvrages d’histoire des sciences, des Origines de la statique (1905) au
Système du Monde (achevé/inachevé en 1916 et publié intégralement
en 1958).

En Égypte, l’université Al-Azhar s’engage pour la liberté religieuse

En Égypte, l’université Al-Azhar s’engage pour la liberté religieuse | manually by oAnth - from its scoop.it contacts | Scoop.it

La plus haute autorité de l’islam sunnite vient d’adresser aux Égyptiens un document où elle souligne la nécessité de respecter les libertés fondamentales du peuple.

À en croire le P. Samir Khalil Samir, il s’agit là d’un « grand pas en avant » pour l’Égypte. Dans une tribune publiée sur le site d’information italien AsiaNews (*), ce jésuite né au Caire en 1938, professeur de sciences religieuses à l’université Saint-Joseph de Beyrouth, décrypte un document diffusé il y a quelques jours par l’université islamique Al-Azhar, au Caire.

Dans cette déclaration dense et argumentée, la plus haute autorité islamique d’Égypte – et l’autorité sunnite la plus influente au monde – se prononce en faveur de la liberté de religion, d’opinion, de recherche scientifique et de créativité artistique. C’est dire si de tels propos sont de nature à rassurer les coptes d’Égypte, alors que le printemps arabe laisse craindre une radicalisation de l’islam égyptien.

C’est le deuxième document présenté par Al-Azhar à la nation égyptienne depuis la révolte de la place Tahrir. Le premier avait été publié le 11 juin dernier. Mais ce nouveau texte aborde de front les points qui inquiètent chrétiens et musulmans modérés, alors que les dernières élections ont validé le poids des Frères musulmans." (François-Xavier Maigre)
