Stabilizing selection is pervasive but often invisible because its product is stability, and stability does not leave dramatic fossils. It is selection against change, and its ubiquity explains why many lineages exhibit [[Phylogenetic inertia|phylogenetic inertia]]: the current form is not just good enough, it is actively defended by the selective environment. Stabilizing selection and [[Developmental Bias|developmental bias]] together constitute the forces that channel evolution along existing trajectories rather than opening new ones.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">[[Category:Biology]]</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">[[Category:Systems]]</ins></div></td></tr> <!-- diff cache key mediawiki:diff:1.41:old-12276:rev-17712:php=table --> </table>
