Adaptationism fails to resolve Fermi's paradox

Abstract

One of the most interesting problems in the nascent discipline of astrobiology is more than half-century old Fermi's paradox: why, considering extraordinary young age of Earth and the Solar System in the Galactic context, don't we perceive much older intelligent communities or signposts of their activity? In spite of a vigorous research activity in recent years, especially bolstered by successes of astrobiology in finding extrasolar planets and extremophiles, this problem (also known as the "Great Silence" or "astrosociological" paradox) remains as open as ever. In a previous paper, we have discussed a particular evolutionary solution suggested by Karl Schroeder based on the currently dominant evolutionary doctrine of adaptationism. Here, we extend that discussion with emphasis on the problems such a solution is bound to face, and conclude that it is ultimately quite unlikely. .Jedan od najinteresantnijih problema u mladoj oblasti astrobiologije jeste vise od pola veka stari Fermijev paradoks: zasto, kad uzmemo u obzir malu starost Zemlje i Suncevog sistema u galaktickom kontekstu, ne zapazamo daleko starije inteligentne zajednice ili tragove njihove aktivnosti? Uprkos snaznoj istrazivackoj aktivnosti u poslednjim godinama, posebno podstaknutim uspesima astrobiologije u pronalazenju ekstrasolarnih planeta i ekstremofila, ovaj problem (takodje poznat kao problem "Velike tisine" ili "astrosocioloski" paradoks) ostaje otvoren kao i uvek. U prethodnom clanku, razmatrali smo jedno konkretno evoluciono resenje koje je predlozio Karl Sreder na bazi danas dominantne evolucione doktrine adaptacionizma. Ovde mi prosirujemo tu studiju sa naglaskom na probleme sa kojima se takvo resenje suocava, i zakljucujemo da je ono u krajnjem ishodu malo verovatno. .
