Parallel evolution was an evolutionary process by which separate groups of organisms occupying different but equivalent environments developed similar adaptations or characteristics for survival.

The Twelfth Doctor cited this as the process that led to the independent development of several factions of Cybermen on various planets throughout time and space, including Mondas (and on a Mondasian colony ship), Telos, Earth, Planet 14, and Marinus. (TV: The Doctor Falls)
Daleks
When later historians and scientists discovered Bryant Anderson's research that suggested that the Daleks were descended from humans transplanted onto Ameron, parallel evolution was suggested as an explanation to reconcile this with the known history of the Daleks being native to Skaro.

Qualen came to believe that the Daleks were destined to arise whether regardless of the the Doctor's involvement; based upon Davros' own research, he believed that the ongoing nuclear civil war on Skaro would have inevitably resulted in the creation of the Daleks "or something very like them." (PROSE: The Dalek Problem) Indeed, the Dalek Prime once claimed Davros had interfered with their development by bringing them into being earlier than they were destined to, (PROSE: War of the Daleks) although Davros proclaimed at other times that the Daleks only acted the way they did because he made them in his own image. (AUDIO: The Davros Mission, et. al)
Human historians in the post-Time War universe were aware of conflicting accounts of the creation of the Daleks which did not involve Davros, most notably their creation at the hands of Yarvelling, a scientist of the blue-skinned Humanoid Daleks. Historians suggested that these alternative "origin stories" may have temporarily became true as the Time Lords "reached back to reconstruct the past" during the Time War.

When Marc Cory explained to Gordon Lowery that vargas on Kembel meant the Daleks were there, Lowery suggested that they could've grown naturally via parallel evolution or even been transplanted, but Cory explained they were developed in Dalek laboratories. (PROSE: Mission to the Unknown)
