Explanation:

La estructuras análogas (por ejemplo, órganos, tejidos, etc) son aquellas que cumplen la misma o similares funciones pero que poseen un origen evolutivo distinto (es decir, no comparten un antepasado común) y son producto de la convergencia evolutiva. Por el contrario, estructuras homólogas son aquellas que se caracterizan por tener un origen evolutivo común (comparten un antepasado común), independientemente de la función que cumplan. Las estructuras análogas se caracterizan por tener diferentes orígenes embrionarios y planes de construcción distintos (es decir, las células que dan origen a este tipo de estructuras son de linajes diferentes). Un ejemplo bien conocido de estructuras análogas son las alas de mariposas y murciélagos, las cuales cumplen la misma función pero no derivan de un antepasado común.
