驱动蛋白马达与智能进化

Kinesin Motors and the Evolution of Intelligence

J. C. Phillips

摘要:

智力经常被讨论为大脑皮层的神经网络,其进化可能受到达尔文选择的影响。在这里,我们提出的分子证据表明,许多驱动蛋白马达之一,Kif14,已经演变成在其氨基酸序列中表现出特殊的功能,可以进化到改善神经网络。通过比较12个物种的Kif14序列来量化改进。其特点是基于几个亲水尺度的水波剖面中疏水极值的水平集。最有效的尺度是基于分形的新尺度,表明球状曲率接近自组织临界性。

英文摘要:

Intelligence is often discussed in terms of neural networks in the cerebral cortex, whose evolution has presumably been influenced by Darwinian selection. Here we present molecular evidence that one of the many kinesin motors, Kif14, has evolved to exhibit special features in its amino acid sequence that could have evolved to improve neural networks. The improvement is quantified by comparison of Kif14 sequences for 12 species. The special feature is level sets of hydrophobic extrema in water wave profiles based on several hydropathic scales. The most effective scale is a new one based on fractals, indicative of approach of globular curvatures to self-organized criticality.
