Reptiles first arose from earlier tetrapods in the swamps of the late Carboniferous (Early Pennsylvanian – Bashkirian). Increasing evolutionary pressure and the vast untouched niches of the land powered the evolutionary changes in amphibians to gradually become more and more land-based.[1]

This is what most people mean when they say that birds are reptiles, although technically, according to the phylogenetic system, birds, reptiles, and mammals all share a reptile-like ancestor.[8]
What Are The Similarities Between Mammals And Amphibians?

Both mammals and amphibians consist of a notochord, dorsal central nervous system, pharyngeal gill slits, and a post-anal tail. Both mammals and amphibians are deuterostomes with bilateral symmetry. Both mammals and amphibians have two eyes with colored vision.[9]
What Do Reptiles And Humans Have In Common?
Lizards and humans share similar brain parts, which they inherited from fish. These parts handle basic body functions like breathing, balance, and coordination, and simple survival urges like feeding, mating, and defense.[10]
What Are The Tough, Leathery Eggs Of Reptiles And Birds Called?
In reptiles and birds, the amnion, chorion, and allantois are further protected by a hard or leathery calcareous shell.[11]
What Are Tough Leathery Eggs Of Reptiles Called?
Amniotic Eggs
They also provide it with a rich, fatty food source (the yolk). The amniotic egg is an important adaptation in fully terrestrial vertebrates. It first evolved in reptiles. The shells of reptile eggs are either hard or leathery.[12]
Which Eggs Are Leathery?
Most reptile eggs are leathery. It protects them when laid in holes, where they drop into contact with other eggs and it serves to make them more resilient, when covering the eggs with sand, dirt and other debris to conceal them.[13]

Which Reptiles Lay Hard Eggs?
Hard-Shelled Varieties
Most turtles, for example, lay leathery eggs, but a few lay hard eggs, such as stinkpots and mud turtles. Many tortoises lay hard eggs, as do geckos. Crocodiles deposit hard eggs as well.[15]
Why Are Reptiles Not Dependent On Water Like Amphibians
Reptiles are not dependent on water because they produce amniotic eggs and breathe using their lungs only.[16]
Why Are Reptiles Independent Of Water?
Reptile skin is a solid sheet of keratin scales. Keratin is the same substance as human hair and nails. This makes it waterproof and prevents the reptile’s internal fluids from evaporating.Nov 22, 2019[17]
Why Are Reptiles More Independent From Water Than Amphibians?
Living on land means reptiles can’t rely on absorbing oxygen through their skin like amphibians. All reptiles have lungs they use for breathing — even those who live most of their lives near or in water, such as crocodiles, must surface to breathe. Lungs allow reptiles to venture far away from aquatic environments.[18]
Why Do Reptiles Not Need Water To Reproduce?
Most reptiles reproduce sexually and have internal fertilization. Reptile eggs are amniotic, so they can be laid on land instead of in water.[19]
Why Are Reptiles Not Amphibians?
Reptiles have scales, and their skin is dry. Amphibians do not, and their skin is often moist with mucus, which keeps them from drying up.[20]
What Is The Difference Between Uva And Uvb Light For Reptiles
UVA light helps regulate behaviors such as feeding, diurnal movement, mating and similar activities. UVB light allows the synthesis of vitamin D3, which helps to absorb calcium. UVC light is not required for reptiles, but it can help kill bacteria.[21]
Is A Basking Light Uvb Or Uva?
While many basking lamps provide UVA light and heat, they don’t give out UVB light. You will need to purchase and set up a separate UVB light. Different basking and UVB lights will also be different strengths and wattages.[22]
What Type Of Light Is Best For Reptiles?
Metal Halide Bulbs are the absolute best UV source for your pet reptile on the market. Combining optimal levels of UVA, UVB, visible light, and heat, Metal Halide Bulbs are simply the best. A Metal Halide Bulb will bring out natural behaviors in your pet reptile, as well as increase it’s coloration and overall health.[23]
What Type Of Uv Light Do Reptiles Need?
A UV light source should emit light in the UV-B range (290-320 nanometers). UV-A light (320 – 400nm), although important in terms of behavior, does not aid in the manufacture of vitamin D3. Most bulbs sold for use in reptiles provide both UV-A and UV-B.[24]

Chapter 32 Flashcards | Quizletquizlet.com › Science › Biology › Zoology[25]
What Is True For Reptilia?
In reptiles, external ear is absent; the ear is represented by a tympanum. Most reptiles have a three chambered heart, except crocodiles, which have a four chambered heart. Reptiles are poikilotherms (cold-blooded), and oviparous (egg-laying).[26]
Which Of The Following Statements Best Represents Evidence Supporting The Leading Hypothesis Regarding The Evolution Of Jaws In Vertebrates?
Which of the following statements best represents evidence supporting the leading hypothesis regarding the evolution of jaws in vertebrates? Both jaws and gill supports are derived from the same type of specialized embryonic cells.[27]
Which Of The Following Statements About Bone Found In Early Vertebrates Is Correct?
Not all chordates can live on land. Which of the following statements about bone found in early vertebrates is correct? The bone in early vertebrates formed protective plates on the surface of the animal. The bone found in early vertebrates was not in an endoskeleton.[28]
What Is The Difference Between Mammals And Reptiles
Mammals have hair all over their bodies, while reptiles have scales. Mammals have live births and produce milk for their young, while reptiles lay eggs. Reptiles have only three-chambered hearts, mammals have four. Reptiles will continue growing throughout their lives and continually replace lost teeth.[29]
What Is The Difference Between Mammals Reptiles And Amphibians?
Birds belong to class Aves, mammals belong to Mammalia, reptiles to Reptilia and amphibians to Amphibia. Birds and mammals are warm-blooded, while amphibians and reptiles are cold-blooded. This means that birds and mammals can regulate their own body temperature, while amphibians and reptiles cannot.[30]
