Scientific Elite

The Scientific Elite was a team of Kaleds trying to develop a way to win their war against the Thals. The head of the Elite was Davros and every member of the Elite was loyal to their cause.

Thousand year war
The elite developed technology for the war effort; they created a protective field for the civilian dome.

Dalek project
The elite knew that their race would eventually evolve into something else and Davros was designated to create a machine in which the new Kaleds could live in. This he developed and called the Mark III Travel Machine, which he could control by remote and could give it independent control. This new development could be used to defeat the Thals, and he later announced that the Mark III Traveling Machine would called a "Dalek".

The Elite saw that Davros was turning the Dalek into a creature of evil, and as this would have intervened with their evolution, they turned against Davros after the Kaled Dome was destroyed (thanks to Davros giving the Thals the formula).

They presented Davros with a choice: either give the Dalek emotions and a sense of right and wrong, or work on the Daleks would stop and they would be destroyed. Eventually, the Elite were divided into those who remained loyal to Davros and those who were against him. During that time, Davros had been remotely calling his Daleks to the bunker in which he and the Elite were in. When the Daleks arrived, they exterminated all those who were not loyal to Davros, but soon afterwards found that they were the superior beings, even to Davros. They exterminated the rest of the Elite, Davros' assistant Nyder, and then Davros himself. (DW: Genesis of the Daleks)
