Adaptive radiation often occurs after a mass extinction. If you were examining fossil beds and found evidence of the rapid appearance of new species in an apparent adaptive radiation event, could you conclude that a mass extinction had occurred?

Question

Adaptive radiation often occurs after a mass extinction. If you were examining fossil beds and found evidence of the rapid appearance of new species in an apparent adaptive radiation event, could you conclude that a mass extinction had occurred?

yes because the presence of adaptive radation means that there must have been newly vacated riches to

yes because the appearance of new species always means that adaptive radiation has occured, and no further data is needed to ans particular question

no because speciation and adaptive radiation can occur for other reasons, such as substantial environmental changes, you would need caters to know more

no because there is not enough evidence to know whether specion occured

Answer 1

The best answer here is: no because speciation and adaptive radiation can occur for other reasons, such as substantial environmental changes, you would need caters to know more. It is important to consider other factors and gather more evidence before concluding that a mass extinction had occurred solely based on the rapid appearance of new species in a fossil bed.
