Study uncovers lost 'golden age' of languages

3 days ago

A linguistic 'golden age' occurred 1,000 to 3,000 years ago with tens of thousands of languages spoken worldwide.
The decline in linguistic diversity started with the rise of large states and empires, not just European colonialism 500 years ago.
Today's roughly 7,600 languages are a historically biased sample of past languages due to selective survival.
The study combined ethnographic data, prehistoric population estimates, and modeling to trace language diversity over 12,000 years.
Political currents are not unidirectional, so endangered languages are not inevitably doomed to extinction.

Learning another language could slow brain ageing by up to 13 years.
Speaking multiple languages is associated with younger-appearing brains, with more languages and earlier acquisition linked to greater benefits.
Study of 728 people used AI and brain scans to measure connectivity, finding multilingualism delays age-related decline in memory and speed of thought.

Languages can feel familiar due to practical usage patterns, not just historical family trees.
A subtitle-based similarity map analyzed how languages translate the same English phrases, revealing cross-family links.
Examples like Finnish and Swedish show proximity from cultural contact, not shared ancestry.

Scientists previously believed human evolution had slowed or stopped after civilization, but new research shows rapid genetic changes in the last 10,000 years.
Using the largest collection of ancient human DNA, researchers identified 479 genes under natural selection, with evolution accelerating in the past 5,000 years.
A Genetic Relationship Matrix helped filter out noise from migration, revealing clear signals of natural selection in genes related to immunity, baldness, and blood type.

Understanding goes beyond mere knowledge, requiring a moment of deep connection with truths.
The moon, Jupiter, and Venus symbolize a shared celestial view across history, highlighting our limited human perspective.
Words and stories are powerful tools for communication and understanding, rooted in our innate desire for narrative.

A 2007 study debunked the claim that women talk more than men, finding both genders speak about 16,000 words daily.
A 2024 replication with over 2,000 participants confirmed equal talkativeness but found a 20% decline in daily words to 12,700, dropping about 338 words per year.
Possible reasons for the decline include replacement by digital communication, reduced casual interactions like asking for directions, and fewer conversations with strangers.
