TED२००७ मा भौतिक विज्ञानको शालिन  कुरा गरेपछि, बिचित्रका गेल-म्यानले अर्को उत्साहजनक रुचि: आधुनिक भाषाहरूको साझा पूर्वज पत्ता लगाउने बारेमा छोटो समीक्षा गर्छन।

मुरे गेल-म्यान-- भाषाको पूर्वजको बारेमा

Modern languages might trace back to a single ancestor spoken over 20,000 years ago, far beyond familiar language families. Observations of ancient cave paintings and sculptures from 35,000 years ago suggest that complex communication existed even then. While most Western linguists avoid exploring deep linguistic relationships, some researchers persist in chasing this mystery. The search for language's roots may reveal a profound bottleneck in human history.
