It does to a great extent. Thanks for the clarification - so the Shudras according to this evolution - may have taken the wrong Karma paths in the their previous lives, so being born in this current state.
God, Soul and Nature (Prakriti) are three eternal entities that always existed and will always exist according to vedas...evolution that vedas speak of are during one's lifetime.

Many examples exist of change of Varnas in Vedic history.
a. Aitareya Rishi was son of a Daasa or criminal but became a Brahmin of highest order and wrote Aitareya Brahman and Aitareyopanishad. Aitareya Brahman is considered critical to understand Rigveda.
b. Ailush Rishi was son of a Daasi, gambler and of low character. However he researched on Rigveda and made several discoveries. Not only was he invited by Rishis but also made an Acharya. (Aitareya Brahman 2.19)
c. Satyakaam Jaabaal was son of a prostitute but became a Brahmin.
d. Prishadh was son of King Daksha but became a Shudra. Further he did Tapasya to achieve salvation after repenting.
(Vishnu Puran 4.1.14)
Had Tapasya been banned for Shudra as per the fake story from Uttar Ramayan, how could Prishadh do so?
e. Nabhag, soon of King Nedishtha became Vaishya. Many of his sons again became Kshatriya. (Vishnu Puran 4.1.13)

j. Haarit became Brahmin though born to Kshatriya (VP 4.3.5)
k. Shaunak became Brahmin though born in Kshatriya family. (VP 4.8.1). In fact, as per Vayu Puran, Vishnu Puran and Harivansh Puran, sons of Shaunak Rishi belonged to all four Varnas.
