This exoskeleton\u00a0<strong>serves as both<\/strong>\u00a0<strong>protection and structural support<\/strong> for their bodies.<\/li>\n<li><strong>Segmented Bodies<\/strong>: They have s<strong>egmented bodies, which are divided into distinct regions,\u00a0<\/strong>including the head, thorax, and abdomen in insects.

They are characterized by the presence of a vertebral column or backbone, which is made up of a series of individual bones called vertebrae. This backbone provides structural support and protection for the spinal cord, which is a key part of the central nervous system. Vertebrates are known for their complex and well-developed internal structures.\u00a0<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/www.news9live.com\/science\/scientists-study-exquisitely-preserved-three-eyed-predator-from-520-million-years-ago-2272792\" target=\"_blank\" rel=\"nofollow noopener\"><u>Scientists study exquisitely preserved three-eyed predator from 520 million years ago<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Kylinxia zhang is an extinct arthropod that lived in the early Cambrian period, about 520 million years ago.<\/p>\n","protected":false},"author":5,"featured_media":31164,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-31163","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/31163","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=31163"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/31163\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/31164"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=31163"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=31163"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=31163"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
