Excellent thread, albeit wildly OT - I am still enjoying it. I will also add that these changes take time usually over enormous periods of time. I always get a laugh from folks who say that evolution is not real as they cannot see it happening, or if it were real then global warming would not be a problem as life would adapt. They don't understand that the speed of the change plays a major role too - Hell if the dinosaurs could have only adapted faster to that impact, well thinks might be different around here. Usually when we are talking 'speed' on these sort of time scales it might be hundreds of years, rather than tens of thousands. Some folks seem to think it means next week.... Oh well... Can lead them to knowledge, can't make 'em think... -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Stuart McLachlan Sent: Monday, 23 April 2012 7:39 AM To: Access Developers discussion and problem solving Subject: Re: [AccessD] The coming in-memory database tipping point. - SQL Server Team Blog - Site Home - TechNet Blogs It's even more nuanced that that. If a random mutation is favourable within the existing environmental conditions, those possessing the mutation will either survive to breed longer or breed more successfully that those without it. In either case they will have above average numbers of offspring, even if only marginally. Over time that above average number of offspring will mean that more and more of the population contain the mutation, eventually completely displacing those without it. The converse applied to disadvantageous mutations. It is also worth noting that a change in environmental conditions can turn a "bad" mutation ito a "good" one and vice versa (or turn a "good" or "bad" mutation into a neutral one). -- Stuart On 22 Apr 2012 at 15:20, Arthur Fuller wrote: > I don't think that your description of evolution is correct.

Some of them survive and procreate, others do not. -- AccessD mailing list AccessD at databaseadvisors.com http://databaseadvisors.com/mailman/listinfo/accessd Website: http://www.databaseadvisors.com
