Ingen vet exakt hur många massutdöenden som har ägt rum på vår jord. Forskarna har ganska bra koll på de fem största som har inträffat under de senaste 500 miljoner åren – och kanske befinner vi oss nu på randen till ett sjätte, orsakat av människans rovdrift på planeten. Utöver dessa stora massutdöenden har ett antal mindre ägt rum, vars antal varierar beroende på hur begreppet definieras.
