Rise of the Animals: Triumph of the Vertebrates The new frontier for fossil discoveries is China. Here Scientist are able to take evidence for evolutionary theories. The fossil record contains many well-documented examples of the transition from one species into another‚ as well as the origin of new physical features. Evidence from the fossil record is unique‚ because it provides a time perspective for understanding the evolution of life on Earth. David Attenborough embarks on an epic 500-million-year

the most diverse venomous reptiles that we have in the United States. Both of these reptiles are widely used in venom extraction programs around the world. Eastern and Western diamondback rattlesnakes have many similarities and differences related to habitat‚ behavior and venom composition.

Introduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years‚ a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate‚ but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that

The Chameleon‚ Chamaeleonidae‚ is a colorful reptile with a tail and tongue the length of their body. The chameleons extend their tongue roughly one and a half times‚ the length of their body providing them the skill to catch prey without having to move.

Physiological Adaptations of the Plesiosaur for Holding its Breath’ By Nathan Eaton One hundred and fifty million years ago‚ large aquatic species of reptile such as the Plesiosaur dominated the ocean‚ and were pre-eminent predators of the sea. The branch of now extinct Plesiosaurs‚ or near lizards’‚ evolved into variant closely related species specialised to take different niches in the food chain. Such species of Plesiosaur include the phenotypically similar Plesiosauroid and Pliosauroid

Around 4.6 billion years ago‚ our universe was born by accretion from the solar nebula known as the Big Bang. As the sun heated up‚ this orbiting matter accumulated and unavoidable mass of larger bodies collide to successively create protoplanets with its own gravitational pull. During this period‚ Earth was nothing but molten rock from the collision with other bodies and volcanoes‚ temperature reaching over 2‚000 fahrenheit. Not only that‚ but Earth then‚ would’ve been toxic to humans and modern
