Penis skute\u010dn\u011b m\u00e1 n\u011bco spole\u010dn\u00e9ho s prsty. A to nikoli jen podobnost vzhledovou, ale tato souvislost je mnohem hlub\u0161\u00ed – genetick\u00e1.<\/p>\n

Jak objevili \u0161v\u00fdcar\u0161t\u00ed v\u011bdci Nicolas Lonfat, Thomas Montavon, Fabrice Darbellay, Sandra Gitto, Denis Duboule z Katedry genetiky a evoluce na \u017denevsk\u00e9 univerzit\u011b ve \u0160v\u00fdcarsku, pro tvorbu v\u0161ech prst\u016f, v\u010detn\u011b jednoho kter\u00fd z\u016fstal bez kloub\u016f, se \u00fa\u010dastnily stejn\u00e9 geny. V\u011bdci to uvedli v presti\u017en\u00edm \u010dasopise Science. (1)<\/p>\n

V\u011bdci se domn\u00edvaj\u00ed, \u017ee souvislost d\u011bdi\u010dn\u00fdch mechanism\u016f byla polo\u017eena v d\u00e1vn\u00fdch dob\u00e1ch, kdy \u017eivo\u010dichov\u00e9 vym\u011bnili mo\u0159sk\u00fd \u017eivot za \u017eivot na sou\u0161i. Ale nen\u00ed zde prostor na ot\u00e1zku: Co bylo d\u0159\u00edve – zevn\u00ed genit\u00e1l nebo prsty. I kdy\u017e se zd\u00e1, \u017ee logika nazna\u010duje, \u017ee prsty by sotva byly vhodn\u00e9 pro reprodukci.<\/p>\n

Mimochodem, Clifford Tabin a jeho kolegov\u00e9 z katedry genetiky na Harvard Medical School v jin\u00e9 studii zjistili: u had\u016f a je\u0161t\u011brek se zevn\u00ed genit\u00e1l vytv\u00e1\u0159\u00ed ze stejn\u00e9 l\u00e1tky jako zadn\u00ed kon\u010detiny. A u savc\u016f \u2013 ze z\u00e1rode\u010dn\u00fdch bun\u011bk ocasu. To vysv\u011btluje, pro\u010d u plaz\u016f jsou dva penisy a u savc\u016f, v\u010detn\u011b \u010dlov\u011bka, jeden. Proto, \u017ee m\u00e1 zadn\u00edch kon\u010detin dv\u011b a ocas – jeden.<\/p>\n

Trochu historie. P\u0159i hled\u00e1n\u00ed vn\u011bj\u0161\u00edch p\u0159\u00edznak\u016f, podle kter\u00e9ho by se mohlo usuzovat na velikost mu\u017estv\u00ed, v\u011bdci, a za nimi i dal\u0161\u00ed z\u00fa\u010dastn\u011bn\u00e9 strany (obvykle \u017eeny) bylo vyzkou\u0161eno ji\u017e mnoh\u00e9. Sna\u017eili se usuzovat podle rozm\u011br\u016f nosu – pokud byl dlouh\u00fd a masit\u00fd, m\u011blo by se o\u010dek\u00e1vat, \u017ee stejn\u00fd je i intimn\u00ed org\u00e1n. Stejn\u011b se tak uva\u017eovalo o velikosti chodidla. Nebo podle hustoty vlas\u016f na t\u011ble \u2013 u hol\u00fdch hlav se o\u010dek\u00e1valo n\u011bco fenomen\u00e1ln\u00edho!
