Is Aptos an ERC20?

Could you please clarify whether Aptos is indeed an ERC20 token? It's a question that's been floating around in the crypto community, and I'd appreciate your expert insight on this matter. As you're well-versed in the field of cryptocurrency and finance, I'm curious to know if Aptos adheres to the ERC20 standard, which is a widely-used technical standard for smart contracts on the Ethereum blockchain. If not, could you elaborate on what makes Aptos unique and how it differs from ERC20 tokens?
