I looked at this BBC article briefly and it quickly headed off into territory that did not interest me. Did religion evolve? Are the authors asking the right questions about the issue? They use several premises that seem meaningless to me. In one, they use Bonobos (a type of Ape) and the fact that they 'food share' as a type of religious conduct.
You are welcome to read the article. I think it will likely appeal most to the non religious. Still, I ask the question of where did religion come from? Were Adam and Eve religious? They knew and had talked to God, why would they need religion? Was Abraham religious? Was Moses or Job? What about David or Solomon? Remember that David had Jonothan who apparently did the religious book keeping.
Then eventually Jesus came along and we were given instruction. Looking back, was the contact that Moses had with God in the Desert religion?
As I think about it, perhaps I don't want religion. Perhaps what I want is to sit with God, be instructed by him, corrected for my mistakes, taught his plans, and know if there is a way for me to support that. To show love and respect, and to live up to his expectations?

All the prophets had same religion with same pillars of faith (same message)

In every era and development in a particular ceiling, the prophets come to develop new laws that accompany the way of life they live.
The last laws was Islam because it is consistent with the official way of life that God wants and it is the last mitigation that God can accept for human (according to the principles of Islamic laws)
