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?\nanalogous structures\nhomologous structures\nvestigial structures\nmutated structures
Answer
Answer:
A. analogous structures
Brief Explanations:
Analogous structures have similar functions but different evolutionary origins. Since Thylacosmilus and Smilodon don't share a saber - tooth ancestor but have saber teeth, they are analogous. Homologous structures have a common ancestor origin, vestigial structures are remnants with reduced function, and there's no indication of mutation - related origin here.
