Why might planets around high-mass stars have too little time for advanced life to develop?

Planets orbiting high-mass stars may lack sufficient time for advanced life to develop because these stars have relatively short lifespans. While smaller stars like the Sun can remain stable for billions of years, high-mass stars exhaust their nuclear fuel much more rapidly, with lifetimes often measured in only millions of years.12

Because the evolution of advanced life on Earth required billions of years, the brief lifespan of a high-mass star means that even if an Earth-like planet formed within the star's habitable zone, the benign environmental conditions necessary for life to emerge and evolve would not persist long enough. Consequently, the star would likely reach the end of its life—often culminating in a supernova explosion—before complex organisms could fully develop.13
