{"product_id":"2940156768400","title":"Evolution of fish","description":"The evolution of fish began about 530 million years ago during the Cambrian explosion. Early fish from the fossil record are represented by a group of small, jawless, armoured fish known as ostracoderms. Jawless fish lineages are mostly extinct. An extant clade, the lampreys may approximate ancient pre-jawed fish. The first jaws are found in Placoderm fossils. The diversity of jawed vertebrates may indicate the evolutionary advantage of a jawed mouth. It is unclear if the advantage of a hinged jaw is greater biting force, improved respiration, or a combination of factors.","brand":"Euprint press Limited","offers":[{"title":"Default Title","offer_id":47103728386288,"sku":"2940156768400","price":1.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940156768400_p0.jpg?v=1764087332","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940156768400","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
