From the article: "Fitch’s experiments were inconclusive on the subject of whether Chomsky’s universal grammar applied to the Pirahã" And Tecumseh Fitch is the one who developed a concept of Recursion in linguistics. How do you explain that?

"Vocal learning, the substrate of human language, is a very rare trait. It is known to be present in only 6 groups of animals: 3 groups of birds (parrots, songbirds, and hummingbirds) and 3 groups of mammals (bats, cetaceans[whales/dolphins], and humans).

All other groups of animals are thought to produce genetically innate vocalizations.

To understand this concept, it is important to distinguish vocal learning from auditory learning. Auditory learning is the ability to make sound associations, such as a dog learning how to respond to the sound "sit". All vertebrates have auditory learning.

Vocal learning is the ability to imitate sounds that you hear, such as a human or a parrot imitating the sound "sit". Currently only vocal learners have been found to have forebrain regions dedicated to vocal learning and production of these learned vocalizations. Vocal non-learners only have been found to have non-forebrain vocal regions responsible for the production of innate vocalizations." http://www.jarvislab.net/Evolution.html

The ancestor of the elephants was aquatic and had a similar lifestyle to a hippopotamus http://en.wikipedia.org/wiki/Elephant#Evolution

An ignition indicates that the car has an internal combustion engine.

The speech-enabling gene FOXP2 indicates that there are brain circuits that make vocal learning possible.

The question is why this gene is present in aquatic mammals and is absent in terrestrial apes

People with mutation in this single gene lose the ability for vocal learning and speech. How do you explain that?

First of all, this theory is not stupid.

Humans belong to a small number of animal groups that display vocal learning.

Vocal Learning Animals have a special “language” gene ( FoxP2 ), that gives them the ability to learn and imitate sounds they hear.

Among mammals only Dolphins, Whales, Seals, Elephants and Humans have FoxP2 gene. All of them are aquatic animals or have aquatic ancestors.

Good advise

I think it all depends on people's personality type. Extrovert will be more successful when he lives in a startup hotbed. Introvert doesn't need anybody, he can live anywhere he likes.
