About this document
Evolutionary Traits of Chordates by lbeltz0001 is a document available to read on EtoBox.
Chordates are characterized by four key features during development: notochord, dorsal hollow nerve cord, pharyngeal gill slits, and post-anal tail. Vertebrates evolved from jawless fish, progressing through various forms including jawed fish, amphibians, reptiles, birds, and mammals, each adapting to different environments. Mammals are distinguished by features such as hair, mammary glands, and varying reproductive strategies, with humans appearing approximately 200,000 years ago.
