Thekey differencebetween spatial sorting and natural selectionis that special sorting filters the基因型based on the dispersal rate while natural selection filters the genotypes based on the reproductive rate.
Traits evolve through generations, facilitating the survival and再生产of organisms. Natural selection is the basic mechanism of evolution. Spatial sorting is also a mechanism that is evolutionarily important. Spatial sorting operates through space, while natural selection operates through time.

What is Spatial Sorting?
Spatial sorting is a mechanism of evolution that filters the genotypes on the basis of dispersal rate. Therefore, it operates to filter the genotypes through space.特征或基因与分散有关的是这种现象中的主要关注点。分散的成功或生物体的分散率取决于几种特征,例如速度,耐力和方向运动。具有快速分散能力的生物会在个人面前繁殖,从而缓慢分散。因此,不断发展的人群的分散后代更快。后代通过这种特征的托管来发展越来越快地分散。
自然选择是什么?
自然选择是查尔斯·达尔文(Charles Darwin)于1859年开发的进化的关键机制。它会过时的基因型。它与差异终生生殖成功的概念有关。自然选择根据生殖速率过滤生物。由于自然选择,生物的种群随着时间的流逝而适应其环境。
根据自然选择理论,拥有比其他人更适合环境的特征的个体更有可能生存和繁殖。他们将这些适应性特征传递给了他们的后代。同样,通过自然选择,有利的特征是世代相传的。自然选择解释了随着时间的流逝,不同的生命形式是如何从共同祖先发展而来的。
What are the Similarities Between Spatial Sorting and Natural Selection?
- Spatial sorting and natural selection are two mechanisms of evolution.
- These two phenomena interact with each other strongly.
- Both natural selection and special sorting happen in every generation.
- They require heritable variation.
- Both result in deterministic shifts in phenotypic attributes.
What is the Difference Between Spatial Sorting and Natural Selection?
Spatial sorting is an evolutionary mechanism that operates to filter the genotypes based on their dispersal rate. On the other hand, natural selection is a key mechanism of evolution that operates to filter the genotypes based on their reproductive rate. So, this is the key difference between spatial sorting and natural selection. Moreover, spatial sorting filters the organisms through space while natural selection filters the organisms through time.
The following figure summarizes the difference between spatial sorting and natural selection in tabular form for side by side comparison.
Summary – Spatial Sorting vs Natural Selection
Spatial sorting filters out organisms through space while natural selection filters out organisms through time. Dispersal rate is the main concern in spatial sorting while reproductive rate is the main concern in natural selection. Thus, this is the summary of the difference between spatial sorting and natural selection. Both spatial sorting and natural selection interact with each other strongly in evolution. Therefore, genotypes having both temporal and spatial aspects to their fitness successfully appear and evolve in successive generations. Both mechanisms influence the evolution of traits over generations.
