Cómo explican Lamarck y Darwin el origen del cambio del cuello de las jirafas?

In the early 19th century, French naturalist Lamarck explained that the giraffe's neck and legs became longer as it was picking leaves from higher and higher places. Darwin and Wallace refuted Ramarck's claim that the acquired traits were inherited, explaining that a long-necked giraffe appeared first and such a giraffe flourished because it could eat leaves higher than a short giraffe.

A principios del siglo XIX, el Naturalismo francés Lamk explicó que se alargó el cuello y las piernas de la jirafa para recoger las hojas de un lugar cada vez más alto. Darwin y Wallace refutan las alegaciones de Rama de que el tipo de adquisición es genético, y la jirafa de cuello largo apareció primero y explicó que esas semillas se pueden comer en lugares más altos que cortos.
