En realidad, justamente en ST TNG (la nueva generacion) sí hablan de la
evolucion en varias ocasiones, pero siempre como teoría y no como dato
cierto. Esto da lugar a que en varios casos presenten mundos de "evolucion
dirigida" por una especie superior, e incluso en un capítulo doble (cuyo
nombre lamentablemente no recuerdo) descubren que todos los humanoides en
realidad comparten un origen comun dado por una especie ultraevolucionada
que hacía miles de millones de años "sabía" que el universo iba a implotar y
re-explotar, decidiendo entonces desparramar sus genes en, bueno, el
pre-big-bang y así justifican que la mayoría de las especies inteligentes
fueran humanoides y hasta pudieran mezclarse.

Sin embargo, en TOS (la serie original) presentan muchos más seres
inteligentes completamente distintos a nosotros, incluyendo en la relación
masa encefálica/peso corporal, lo mismo pasa en VGR y DS9, mientras que ENT
vuelve a la tradición humanocentrista (?) y todos son humanoides...

and intelligence: SETI study




Estoy totalmente de acuerdo contigo Anabel, Star Trek es
impresionante en cuanto a exposición de ideas supermodernas sobre
los conceptos de la vida y muchas ramas de la ciencia como
psicología, física, biología y especialmente sobre el funcionamiento
del cerebro. En concreto sobre evolución más que explicar nada
concreto nos pone delante de un mundo que habla por sí solo y por
supuesto no citan para nada la evolución por mutaciones.
Para mí, Star Trek ha hecho más por la evolución del pensamiento
humano que nadie por haber conseguido llevar todos estos conceptos
más o menos filosóficos a grandes capas de población.
Me refiero sobre todo a la seria "Star Trek - The Next Generation".
Recuerdo cuando vi por primera vez esta serie, allá por 1990/91 que
me encantó porque en algunos casos me sorprendió el encontrar ideas
similares a las mías por primera vez, y desde luego no me las
copiaron :)
