what is the difference between class reptilia and clade reptilia?

A clade includes an ancestral species and all its descendants. Linnaean class Reptilia is not a clade because it does not include modern birds. ... Clades Reptilia and Aves, however, are monophyletic and, therefore, valid clades.

There is no difference between a Komodo dragon and a monitor lizard because a Komodo dragonis a monitor lizard. However, just like the way you and your cousins don't all look alike or share certain family traits, there is a difference between a Komodo dragon and other monitor lizards.

The key difference between phenetics and cladistics is the method used in classifying organisms. Phenetics classifies organisms based on morphological and structural features while cladistics classifies organisms based on their ancestry and evolutionary relationships.

Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species, the family Scincidae is one of the most diverse families of lizards.

Actually, birds and mammals are technically reptiles, as they descended from the very first reptile. However, when we calibrate our microscope appropriately, we find that birds are more intimately related to dinosaurs, as they branched off from a dinosaur.

Most classifications categorize pythons in the family Pythonidae; while a few list them in the family Boidae and subfamily Pythonidae. So for practical purpose, boas represent a group of snakes; anacondas are a type of boa within that group; and pythons are a closely-related but different kind of snake.

Hi; In modern times, yes the dragon is classified as part of the reptilian family due to its scaly skin, cold-blood and air-breathing creature that laid eggs containing it's offspring. In old times, the dragon was always called a serpent, as the word reptile wasn't created until science became much more advanced etc.

Well, actually, there's a meaningful difference between tortoises and other turtles. All tortoises are in fact turtles—that is, they belong to the order Testudines or Chelonia, reptiles having bodies encased in a bony shell—but not all turtles are tortoises.

According to the phylogenetic classification system, a reptile is any animal which originated from the original group of reptiles, technically including birds and mammals. Therefore, birds are considered reptiles under Phylogenetic taxonomy, just as other animals that descended from vertebrates are called vertebrates.

is that phylum is (biology|taxonomy) a rank in the classification of organisms, below kingdom and above class; also called a division, especially in describing plants; a taxon at that rank while clade is (biology|systematics) a group of animals or other organisms derived from a common ancestor species.

A clade is a group that includes all the descendents of a common ancestor and that ancestor, and all the different organisms that we think of as fish don't form a clade. ... Scientists use the word "fish" to refer to animals of the same species, regardless of whether there is one individual or 20 individuals.

A clade (/kleɪd/; from Ancient Greek: κλάδος, klados, "branch"), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic—that is, composed of a common ancestor and all its lineal descendants.

Reptiles and amphibians are both animals, many of which have internal fertilization. They both lay eggs. However, reptile eggs tend to have a harder shell while amphibians have soft, permeable eggs, more like fish eggs. A big difference in their development is that amphibians have an aquatic larval form after hatching.

Modern phylogenies place birds in the dinosaur clade Theropoda. According to the current consensus, Aves and a sister group, the order Crocodilia, together are the sole living members of an unranked "reptile" clade, the Archosauria.

is that lizard is any reptile of the order squamata, usually having four legs, external ear openings, movable eyelids and a long slender body and tail while skink is a lizard of the scincidae family, having small or reduced limbs or none at all and long tails that are regenerated when shed or skink can be (obsolete) ...

1 Answer. "Kingdom" a higher taxonomic level, higher than "phylum". You can probably say "superlevel", if you desperately need it in one word, but I would rather say "higher level in the hierarchy/taxonomy/classification".
