Diatoms (microscopic marine plants) are extremely important ecologically (up to 20% of global primary production is due to diatoms) and economically (producing amnesic shellfish poisoning). It is also the most species rich group of microscopic plants with an estimated 200,000+ species. Diatoms are a relatively new evolutionary arrival, suggesting a high rate of speciation. The mechanism(s) of diatom speciation are unknown.

硅藻（微小的海洋植物）具有极其重要的生态意义（全球初级产量的20%来自硅藻）和经济意义（导致失忆性贝类中毒）。它也是物种最丰富的微观植物群，估计有20多万种。硅藻是一种相对较新的进化物种，这表明物种形成的速度很快。硅藻形成的机制尚不清楚。
