It's the other way around, that is, it's the discovery of diversity within unity. Once upon a time, we humans noticed differences while living in unity; then we translated different to mean separate and lost the sense of all being part of unity; now we are rediscovering unity differentiated into many expressions. I became seriously interested in Buddhism about 15 years ago, joined an ongoing study group, learned/read/listened/reflected/meditated Eastern/Vedantic/unitive wisdom, and grew in appreciation of unity and diversity in unity. Diversity means different. Uniformity means the same. Diversity is pervasive. Every one and every thing is a different expression of one Unity. There is no uniformity even if we think there is or try to impose it.
