thylacosmilus is a marsupial, and smilodon is a mammal. thylacosmilus and smilodon both have saber teeth, but they do not share an ancestor that had saber teeth. what are saber teeth for these organisms?\n○ analogous structures\n○ homologous structures\n○ vestigial structures\n○ mutated structures

thylacosmilus is a marsupial, and smilodon is a mammal. thylacosmilus and smilodon both have saber teeth, but they do not share an ancestor that had saber teeth. what are saber teeth for these organisms?\n○ analogous structures\n○ homologous structures\n○ vestigial structures\n○ mutated structures

Answer

Brief Explanations:

Analogous structures have similar functions but different evolutionary origins. Since Thylacosmilus and Smilodon don't share a saber - toothed ancestor but both have saber teeth, their saber teeth are analogous. Homologous structures come from a common ancestor with the same structure in the ancestor. Vestigial structures are remnants with reduced or no function. Mutated structures refer to changes due to mutations, which is not relevant here.

Answer:

A. analogous structures
