A population needs to be small if it is to incorporate any substantial innovation, genetic or cultural; large and dense populations simply have too much genetic inertia to be nudged consistently in any direction. Our own species, the Homo sapiens, was born out of such an event 200,000 years ago, when climate change repeatedly led to fragmentation of hominin populations, creating small groups in which genetic and cultural novelties were rapidly cemented, accelerating speciation. About 100,00 years later an African isolate of our species acquired the ability to use symbols; it was almost certainly this unique symbolic cognition that made it possible to eliminate all hominin competition in little time.

The building blocks required to achieve success in a business domain and differentiate the company from its competitors: Core domains : The interesting problems. These are the in-house activities the company is performing differently from its competitors and from which it gains its competitive advantage. Generic domains : The solved problems. These are the things all companies are doing in the same way. There is no room or need for innovation here; rather than creating in-house implementations, it’s more cost-effective to adopt \ buy existing solutions. Supporting domains: The problems with obvious solutions. These are the activities the company likely has to implement in-house or outsourced, but that do not provide any competitive advantage. Domain experts are subject matter experts who know all the intricacies of the business that we are going to model and implement in code. In other words, domain experts are knowledge authorities in the software’s business domain. T
