通过鲍德温效应的性染色体进化
The Evolution of Sex Chromosomes through the Baldwin Effect
摘要:
最近有人提出,真核生物性别的基本单倍体-二倍体循环利用了鲍德温效应的一种基本形式。此后,其他相关的现象可以解释为进化调整生物体所经历的学习的数量和频率。使用著名的NK模型的适应度景观,它在这里表明,性别决定系统的出现也可以根据真核生物进化的观点来解释。
英文摘要:
It has recently been suggested that the fundamental haploid-diploid cycle of eukaryotic sex exploits a rudimentary form of the Baldwin effect. Thereafter the other associated phenomena can be explained as evolution tuning the amount and frequency of learning experienced by an organism. Using the well-known NK model of fitness landscapes it is here shown that the emergence of sex determination systems can also be explained under this view of eukaryotic evolution.
