How could can humans evolve to have reptilian attributes?

In my world, all of my demihumans have evolved from the same ancestor from modern humans. This conceptually includes my version of Reptilians/Lizardfolk. For the most part I would have them share the same anatomy as regular humans. But they're called lizardmen for a reason. So, if possible, I'd have them have these traits:

• Scales, which can cover most the amount of the body. Maybe some can have patterns and make them have camouflage?
• Long tails that could regenerate.
• Eyes that have color vision and more advanced visual depth perception.
• Claws on their hands, which can be used for tool-making, and reptile-like feet.
• Some may develop venom in their mouth to use as protection.

With all of these attributes in mind, how could they evolve to become the reptillian-ish humanoids I have in mind?
