What animal are crocodiles most closely related to?
birds
Crocodiles are the closest living relatives of the birds, sharing a common ancestor that lived around 240 million years ago and also gave rise to the dinosaurs.
Why are birds closely related to crocodiles?
Although the living reptiles birds are most closely related to are crocodilians (archosaurs), when it comes to their relation to dinosaurs, birds evolved from theropod dinosaurs. These theropods share over 100 traits with modern birds.
Are birds more closely related to mammals or crocodiles?
And they are most closely related to crocodiles, which also came from archosaurs. 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.
What common ancestor do birds and crocodiles share?
Archosauria
Modern paleontologists define Archosauria as a crown group that includes the most recent common ancestor of living birds and crocodilians, and all of its descendants.
Do crocodiles team up with birds?
The researchers noted that crocodilians and nesting birds are often found together throughout the tropics. As such, the mutually beneficial relationship that the scientists discovered “could be a globally widespread and ecologically important interspecies set of relationships,” Nell said.
Are alligators related to birds?
Alligators and birds are part of the same larger group, called archosaurs, which has existed for 250 million years and which has given rise not only to birds and crocodilians, but also to dinosaurs.
Are ducks and crocodiles related?
Modern species share a common ancestor, but are neither descended from each other nor from some crude composite chimera, and ducks are not descended from crocodiles.
Are crocodiles reptiles or birds?
Reptiles are vertebrates that have scales on at least some part of their body, leathery or hard-shelled eggs, and share a number of other features. Snakes, lizards, turtles, crocodilians, and birds are reptiles.
Which traits do birds and crocodiles share?
Birds, crocodiles and dinosaurs have much in common – including, it turns out, their breath. The hyper-efficient breathing system of birds is shared with alligators, and probably evolved in archosaurs, the common ancestor of crocodilians, birds and dinosaurs.
Are crocodiles more closely related to lizards or to birds explain your response?
Based on this evolutionary tree, crocodiles are more closely related to birds than to lizards because they share a more common ancestor with the birds than with lizards.
Are alligators and crocs related?
Family. Alligators and crocodiles are from the same scientific order, but from different families. They are both members of the Crocodylia, but crocodiles are from the Crocodylidae family, while alligators come from the Alligatordae family.
Are crocodiles more related to birds or lizards?
Reptiles comprise a vast animal group of more than 20,000 species. The interrelationships of some subgroups are well understood, the scientists said. Birds are most closely related to crocodilians among living reptiles, for example, while snakes, lizards, and New Zealand’s tuatara form a natural group.
How closely related are crocodiles and birds related?
(Crocodilians are actually more closely related to birds and dinosaurs than they are to other reptiles, i.e., lizards, snakes, and turtles.)
What is the closest living relative to a bird?
(Image credit: Richard E. Green et al.) Crocodiles are the closest living relatives of the birds, sharing a common ancestor that lived around 240 million years ago and also gave rise to the dinosaurs.
