The extinction of hundreds of bird species caused by humans over the last 130,000 years has led to substantial reductions in avian functional diversity—a measure of the range of different roles and functions that birds undertake within the environment—and resulted in the loss of approximately 3 billion years of unique evolutionary history, according to a new study published in Science.
