Which of the groups of animals is common to wetlands?
amphibians, reptiles, migratory birds, small mammals
What is anatomically similar structure inherited from a common ancestor?
The pentadactyl limb structure, found in mammals, birds, reptiles, and amphibians, is inherited from a common ancestor. Despite modifications for different functions, such as wings in birds and flippers in whales, the underlying bone structure remains similar.
Are frogs fish or mammals?
No there is a group call F.A.R (fishes,amphibians, and reptiles). Fishes belong in the fish group and amphibians are double life lives in water and land. Reptiles are Alligators.
What is the most common group of vertebrate animals?
There are seven classes of vertebrates. Three of these are considered fish, and they are the jawless fish, bony fish, and cartilaginous fish. Four live on land, and they are amphibians, reptiles, birds, and mammals.
What is ancestral characters?
An Ancestral Character is a character inherited from a COMMON ancestor. For example the presence of lungs in mammals (an ancestral character) does not indicate that mammals are more closely related to amphibians vs. reptiles, or reptiles vs. birds etc., etc. It is simply a character inherited from a common ancestor.
Are human beings related to reptiles?
Ultimately all organisms are related. Humans are mammals, which are not closely related to reptiles. Mammals and reptiles belong to a group of animals called amniotes, which they also share with birds. Amniotes include all land vertebrates except amphibians. The last common ancestor of mammals and reptiles lived over 300 million years ago in the Carboniferous period. Shortly after the first amniotes branched off from amphibians they split into synapsids, which became the ancestors of mammals, and sauropsids, which became the ancestors of birds and all modern reptiles.
What do reptiles and mammals have in common?
Reptiles and mammals are vertebrates. They both breathe air.
What are some chordata mammals?
All mammals are chordates. Mammals include such animals as humans, dogs, monkeys, etc.
What is an example of common descent?
An example of common descent is the similarities in anatomical structures of different species, such as the pentadactyl limb structure (having five fingers or toes) found in mammals, birds, reptiles, and amphibians. This shared trait suggests that these species have a common ancestor and have evolved from a common lineage.
What are the groups of animals?
Fishes , amphibia ,reptiles , birds , mammals .
What characteristic do reptiles and mammals have in common?
Generally, mammals and reptiles are both vertebrates, meaning they have a backbone and endoskeleton. Reptiles and mammals also have their brains located inside a cranium and have two eyes.
