Question

the distribution and variety of life on island chains challenged the dogma of the stability of species. true false

Explanation:

The statement aligns with the understanding in Biology (specifically evolutionary biology). Island chains often show unique species distributions and varieties that can lead to speciation events, thus challenging the idea of species stability (a concept related to the immutability of species which was a pre - evolutionary biology dogma). For example, Darwin's finches on the Galapagos Islands (an island chain) showed variations in beak shapes and sizes which were a result of adaptation to different ecological niches on the islands, indicating that species are not static.

Answer:

TRUE
