In this world, everyone is either a leader or follower or in some cases both. Means a leader may be follower for some other leader. Everyone posses both leader and follower instincts in their body and mind. Only the proportion of these instincts depicts their nature as a leader or a follower. This concept is pretty similar with the concept of Male and Female hormone in our body.
Usually leaders are few in numbers compared to followers and decide a path and follower (may be blindly) follows that path. This creates a famous tree kind of structure. Also a follower might have more than one leader (remember the multiple inheritance). Now the question is how the chain gets established? Means how a person who is of follower nature, decides which one person from the leaders community is actually his leader? I did some study, analysis and research in that and I believe its just a simple fact that if a person encounters another person which can do/perform or already performed few of the art which he/she couldn't or cannot, he/she accepts him/her as leader. For example, if a person is very much interested in playing soccer but could never became more than an average soccer player, meets a good above average soccer player in his team. He will surely get influenced and major chances are that he will accept him as his leader. If you will think in this line, you can easily validate several leader follower relationships around you with this concept.
So In case you are leading a team of individuals, first analyze every individual or group of individuals about their interests and passion and just try to demonstrate some good qualities in that fields in front of them which will ensure smooth formation of healthy leader-follower chain for you and your team. This is easy way to achieve "self evolved leadership" which is far better than "force imposed leadership" for a team.
At last, some followers are forcibly made leaders for a group of individual and software industry is good example of that :)
