的意思 microevolution

1. Microevolution is the small-scale genetic changes that occur within a population over a short period of time.
微进化是指在短时间内发生在一群体内的小规模基因变化。

2. Natural selection is one of the driving forces behind microevolution, as individuals with advantageous traits are more likely to survive and reproduce.
自然选择是微进化的推动力之一，因为具有有利特征的个体更有可能生存和繁殖。

3. Microevolution can lead to the development of new species over time, as genetic diversity accumulates and populations become reproductively isolated.
随着基因多样性的积累和种群的繁殖隔离，微进化可能导致新物种的产生。

4. Studies have shown that microevolutionary processes can be observed in real time, such as changes in allele frequencies in response to environmental pressures.
研究表明，微进化过程可以在真实时间内观察到，例如对环境压力的反应中等位基因频率的变化。

5. The study of microevolution helps scientists understand how populations adapt to changing environments and how new species arise.
微进化的研究有助于科学家们了解种群如何适应变化的环境以及新物种是如何产生的。

6. Microevolutionary changes can be influenced by factors such as genetic drift, gene flow, mutation, and selective pressures.
微进化的变化可能受到遗传漂变、基因流动、突变和选择性压力等因素的影响。
