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.
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 types of animals can be found in the designated animal area?
Various types of animals can be found in the designated animal area, including mammals, birds, reptiles, and amphibians.
Is homosexuality observed in other species"?
Yes, homosexuality has been observed in many different species in the animal kingdom, including mammals, birds, and insects.
What is homolugous in evolution?
Homologous structures in evolution refer to features that have a similar underlying structure, indicating a shared ancestry despite potentially different functions in different species. These structures are thought to have evolved from a common ancestor and provide important evidence for the theory of evolution. Examples include the pentadactyl limb structure in vertebrates and the similar bone structure in the wings of birds and the limbs of mammals.
Do birds and mammals inherit intelligence from a common ancestor?
yes
Did jaws develop independantly in mammals and birds?
No. Both mammals and birds "inherited jaws" from a common reptilian ancestor which ultimately originated in an early fish.
What are the similarities of human and chicken embryo?
Mammals, birds, and reptiles all derive from a single common ancestor.
How are birds related to mammals?
Mammals and birds are both vertebrates descended from an early reptilian ancestor.
Are cassowaries mammals?
No. They are birds. Birds and mammals are separate classes of animal.
Are cassowary birds mammals?
No. They are birds. Birds and mammals are separate classes of animal.
Are birds and mammals decended from a common ancestor?
Mammals came before birds. The first mammals lived in the Triassic and the first birds lived in the Jurassic.
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.
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.
What do birds and mammals reproduction have in common?
Both birds and mammals care for their young.
Do all mammals have a common ancestor?
Not actually. There were several different marine reptiles that had mammalian characteristics, notably the group known as pelycosaurs. The earliest mammals appeared early in the Age of Reptiles (Mesozoic Era), but were uniformly small in size. The group called synapsids took an evolutionary path to mammals while the sauropsids became today's reptiles and birds.
Are fish monophyletic?
No, fish are not monophyletic. The term "fish" is a paraphyletic group because it includes some but not all descendants of a common ancestor. It does not include tetrapods (four-limbed vertebrates such as amphibians, reptiles, birds, and mammals) which share a more recent common ancestor with some fish species.
