Evolutionary history of organism is studied. • 4- Population or sub-species is emphasized.","styleRuns":[{"startIndex":0,"length":535,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}]},"headerRuns":[{"startIndex":0,"length":535,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"continuationItemRenderer":{"trigger":"CONTINUATION_TRIGGER_ON_ITEM_SHOWN","continuationEndpoint":{"clickTrackingParams":"CK0BELsvGAIiEwjdytPGycuLAxUH50IFHfAmBGo=","commandMetadata":{"webCommandMetadata":{"sendPost":true,"apiUrl":"/youtubei/v1/next"}},"continuationCommand":{"token":"Eg0SC01DN2JMbUc5NmFNGAYyJSIRIgtNQzdiTG1HOTZhTTAAeAJCEGNvbW1lbnRzLXNlY3Rpb24%3D","request":"CONTINUATION_REQUEST_TYPE_WATCH_NEXT"}}}}],"trackingParams":"CK0BELsvGAIiEwjdytPGycuLAxUH50IFHfAmBGo=","sectionIdentifier":"comment-item-section","targetId":"comments-section"}}],"trackingParams":"CKwBELovIhMI3crTxsnLiwMVB-dCBR3wJgRq"}},"secondaryResults":{"secondaryResults":{"results":[{"lockupViewModel":{"contentImage":{"collectionThumbnailViewModel":{"primaryThumbnail":{"thumbnailViewModel":{"image":{"sources":[{"url":"https://i.ytimg.com/vi/-xtMJplbDP0/hqdefault.jpg?sqp=-oaymwEWCKgBEF5IWvKriqkDCQgBFQAAiEIYAQ== rs=AOn4CLABAMVgkJbr_lk234vl_WaGUNjIaw","width":168,"height":94},{"url":"https://i.ytimg.com/vi/-xtMJplbDP0/hqdefault.jpg?sqp=-oaymwEXCNACELwBSFryq4qpAwkIARUAAIhCGAE= rs=AOn4CLB7V3TEHuQhH13L3tTzuHRkZ-stzQ","width":336,"height":188}]},"overlays":[{"thumbnailOverlayBadgeViewModel":{"thumbnailBadges":[{"thumbnailBadgeViewModel":{"icon":{"sources":[{"clientResource":{"imageName":"PLAYLISTS"}}]},"text":"7 videos","badgeStyle":"THUMBNAIL_OVERLAY_BADGE_STYLE_DEFAULT","backgroundColor":{"lightTheme":461875,"darkTheme":461875}}}],"position":"THUMBNAIL_OVERLAY_BADGE_POSITION_BOTTOM_END"}},{"thumbnailHoverOverlayViewModel":{"icon":{"sources":[{"clientResource":{"imageName":"PLAY_ALL"}}]},"text":{"content":"Play all","styleRuns":[{"startIndex":0,"length":8}]},"style":"THUMBNAIL_HOVER_OVERLAY_STYLE_COVER"}}],"backgroundColor":{"lightTheme":857433,"darkTheme":857433}}},"stackColor":{"lightTheme":7041177,"darkTheme":8159131}}},"metadata":{"lockupMetadataViewModel":{"title":{"content":"COELENTERATA"},"metadata":{"contentMetadataViewModel":{"metadataRows":[{"metadataParts":[{"text":{"content":"BIOLOGYGLOBE
