"Evolution of the Daleks" is the fifth episode of the third series of the revived British science fiction television series Doctor Who. It was first broadcast on BBC One on 28 April 2007, and is the conclusion of the two-part story begun in "Daleks in Manhattan".

The Cult of Skaro's plan is in full force. Dalek Sec is reborn in a half-human form, and the Pig Slaves launch an enormous assault upon the Central Park Hooverville along with the remaining pure Daleks. The Doctor, Martha Jones, Solomon and the others must fight for their lives, while the future of humans and Daleks alike is being decided underneath the Empire State Building.

According to the BARB figures this episode was seen by 6.97 million viewers and was the seventeenth most popular broadcast on British television in that week. The story is set in New York City in 1930.

After the creation of the hybrid Dalek-human, The Doctor confronts the Cult of Skaro and uses his sonic screwdriver to help the others escape. Dalek Caan and Dalek Jast discuss their lack of confidence in Dalek Sec, hinting that a change of command may be needed. The Doctor and Martha return to Hooverville, where The Doctor warns Solomon that the Daleks are planning an attack. Solomon believes he can reason with them, but he is killed during the attack. The Doctor confronts Dalek Caan and provokes him, but Dalek Sec orders The Doctor to be brought to him alive.

At the Dalek lab at the Empire State Building, the Doctor learns that the Daleks are planning to combine their DNA with humans and create more hybrids. The process requires more energy than can be generated with the technology of 1930, so the Daleks plan to use gamma energy from a solar flare. The Doctor agrees to help once he realizes that the human subjects are already brain dead and cannot be saved otherwise. He also offers to take the new hybrids and the Daleks to a new planet in the TARDIS so they can start over. Daleks Caan, Jast, and Thay stage a mutiny, chaining up Dalek Sec. The Daleks then decide to replace the human DNA completely with their own, making a new race of Daleks. The Doctor and Laszlo regroup with Martha, Tallulah, and Frank. Martha has analyzed the building plans and tells the Doctor he must remove the Dalekanium panels on the mast of the building to stop the energy collection. The Doctor climbs up, telling Martha to stay behind and fight. As the Doctor struggles to remove the panels, Martha lays out pieces of metal from the framework of the building to connect with the elevator. The Doctor fails to get the panels off in time and ends up holding the mast as the strike hits. The energy flows down the building, electrocuting the Pig Slaves in the elevator but also awakening the new hybrids.
