Eternal Tension of Type vs Diversity

In his book What Evoution Is (the only book of his I have read), Ernst Mayr discusses the shift from typological to population thinking that Darwin introduced. I'm not student of philosophy, but my understanding is that before Darwin, people thought of each animal species as having a defined essence, which idea came from Plato. Darwin drew attention to the biological diversity within each species--no two individuals are exactly alike. To the typologist, the average is real and deviations are unimportant. To the population thinker, diversity is real and the average is just an abstraction.

This has me thinking that there seems to be a tension between typology and population thinking, or diversity. For example, the scriptures are mostly typological. We were created in God's image, we are to be like him, and we are to be "one." This suggests a type or essence that we are, or are striving for. On the other hand, inspite of being in God's image we are quite diverse physically and mentally. Discussion of the degrees of glory and gradation of intelligences are the only scriptures dealing with diversity that come to mind.

Perhaps there is a time for typology and a time for diversity. But this has me wondering what aspects of existance these two paradigms will govern in eternity. How do they govern the resurrection, eternal rewards, our eternal personalities, the perpetuation of mankind in eternity, etc. Are there differences between where gods began to be and where they will be?

Here and now, when should we seek type vs appreciate and embrace diversity?
