Timeline of the far future
Some of these are ironically myopic: &quot;<i>10,000 years: If globalization trends lead to panmixia, human genetic variation will no longer be regionalized, as the effective population size will equal the actual population size. This does not mean homogeneity, as minority traits will still be preserved, e.g. the blonde gene will not disappear, but it will be rather evenly distributed worldwide.</i>&quot;<p>That prediction makes the rather questionable assumption that humans will still be primarily, if not entirely, on Earth in 10,000 years! Interplanetary colonization will likely dwarf the regional evolutionary isolation we&#x27;ve experienced on this planet. In the longrun it will likely even trend towards speciation (as a more reasonable prediction further on does hit on.) Consider that a European, an African, and a Japanese all share an <i>incredibly</i> recent ancestor.<p>The exciting thing about interplanetary colonization is once the technology starts to become robust, our potential growth and expansion is effectively unlimited. It would be like if the western frontier in the US was uninhabited and somehow went on to infinity. The implications of this are difficult to even imagine.
