Question

1. when two organisms share most of their physical and gen

tics, what does the evidence indicate?
they live in the same habitats
they belong to the same order
they descended from a common ancestor
they are the same species

Explanation:

• Physical and genetic similarities are key evidence in evolutionary biology.
• Organisms sharing such traits often have a common ancestor.
• Same habitat doesn't imply genetic/physical similarity.
• Same order is a taxonomic rank but not the best indicator here.
• Being same species is too specific; the question says "most" traits (not all).

Answer:

they descended from a common ancestor
