Were all dinosaurs reptiles?
No way! There were thousands of species of reptiles that lived both during, before, and after the dinosaurs lived on earth. There were the synapsid reptiles, as well as the anapsid reptiles, which were mostly gone when the dinosaurs arrived. There were also many diapsid reptiles that lived during the time the dinosaurs did. Such species include deinosuchus, dimetrodon, gorgonops, Quetzalcoatlus, and rutiodon. Dinosaurs were not reptiles themelves. They evolved from reptiles, many had warm blood even feathers,
Do all mammals have a common ancestor?
Yes, all mammals share a common evolutionary ancestor. Mammals belong to the same taxonomic class, Mammalia, which indicates their common evolutionary heritage. This common ancestor likely existed around 200-230 million years ago.
Is DNA of a lizard more similar to a dog or snake?
The DNA of a lizard is more similar to a snake than a dog, as they are both reptiles. Reptiles share genetic similarities due to their evolutionary history and shared characteristics.
How comparative morphology support theory of evolution?
Look to the morphologies of all mammals and see rather easily how closely related they are in comparison to the more distantly related morphologies of all reptiles. Ancestral traits, such as tetropodal arrangement of limbs and then derived differences between mammals and reptiles. Reptiles having scales and mammals having hair.
Is DNA a characteristic for all living things share?
Yes, DNA is a characteristic that all living things share. To be more precise, all living things share a form of genetic material, which is DNA.
What do all reptiles share?
One characteristic all reptiles share is that they are all cold-blooded.
Do reptiles and birds share enough common characteristics to be classified in the same clade?
Reptiles and birds share enough common characteristics to be classified in the same clade called Sauropsida, which includes all modern reptiles and birds.
Are all dinosaurs reptiles?
All reptiles are diapsids. Mammals (like you and I) are, in contrast, synapsids. So in that respect all reptiles are alike. However, I would not say they were all alike. Snakes are reptiles but lack limbs. Alligators are also reptiles, as are lizards. Tuatara, gavials, amphisbaenids, and tortoises each represent one of the four main modern orders of reptiles. They share some characteristics--just as you and I do, but I would not say they were all alike.
Did humans evolve from reptiles?
No, humans did not evolve from reptiles. Both humans and reptiles share a common ancestor from millions of years ago, but they evolved along separate paths.
Does all reptiles have ribs or not?
no all reptiles does not have ribs
What does A Fish and amphibians and reptiles and mammals and and Birds All Share?
A heart! respiratory systems, all are heteratrophic organisms, all use sexual reproduction (with a few exceptions here and there.)
Which reptiles are vertebrates?
Yes, mammals, birds and reptiles are all vertebrates.
Reptiles and amphibians share a number of features except what?
Mode of reproduction
Do Marsupials share characteristics with other animals from other groups?
Marsupials are mammals, so share all features with other mammals. As well, they are vertebrates, so share the characteristic of having a backbone with birds, fish, reptiles and amphibians. Like birds and reptiles, mammals breathe via lungs (rather than gills), and like birds, they are warm-blooded.
All reptiles have scales?
Yes, all Reptiles do have scales.
Is the hawksbill turtle a mammal?
No, they are reptiles. ALL turtles are reptiles.
What desccribe all reptiles?
all reptiles are cold blooded and are tetrapods
