Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively after a period of apparent absence. Species become extinct when they are no longer able to survive in changing habitat or against superior competition. In Earth's history, over 99% of all the species that have ever lived are extinct; 238] 129] 130] 131] however, mass extinctions may have accelerated evolution by providing opportunities for new groups of organisms to diversify", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/9/79/888/629/9798886294811_b.jpg", "price_data" : { "retail_price" : "13.99", "online_price" : "13.99", "our_price" : "13.99", "club_price" : "13.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
