What else can I help you with?
Did mammals evolve from dinosaurs?
No. Mammals evolved from synapsid reptiles, a group not closely related to dinosaurs. Dinosaurs are more closely related to modern reptiles and birds than they are to mammals.
Are animals related to birds?
Birds are more closely related to reptiles than they are to mammals. Birds, reptiles, and mammals all belong to a group of vertebrates called amniotes, which split off from amphibians. Amniotes split into two groups soon after they evolved: true reptiles and synapsids. Mammals are the only living synapsids today. Dinosaurs branched off from the reptiles and birds then evolved from the dinosaurs.
Why aren't dinosaurs mammals?
Dinosaurs and mammals evolved from two separate branches of reptiles. Mammals evolved from synapisid reptiles (all of which are not extinct) while dinosaurs along with the modern branches of reptiles evolved from sauropsids. So dinosaurs are more closely related to modern reptiles than they are to mammals. In more recent years scientist tend to agree that birds are in fact a surviving branch of dinosaurs.
Do birds and mammals have same lung design?
No. Birds and mammals have radically different lung designs. Birds have a far more complex, but more efficient design than mammals do.
Are mammals related to birds?
Mammals are distantly related to birds. Oddly, if you look at an evolutionary tree, birds are actually more closely related to reptiles than they are to mammals.
Is an egret a mammal or a reptile?
Birds are neither mammals, nor reptiles. They are an entirely different branch of evolution. However, they are more closesly related to reptiles, which they descended from. Their evolution from reptiles caused them to resemble mammals.
How did reptiles pave the way for more land animals?
With skin and egg shells able to retain water, reptiles could remain out of water indefinitely, unlike their amphibian ancestors. Mammals and dinosaurs (from which birds evolved) later evolved from reptiles.
Why are male birds more likely to help care for their babies than male mammals do?
well birds get eating more than mammals so they help care more.
Are birds closest to mammals or reptiles?
While at first glance birds seem similar to mammals, they are more closely related to reptiles.
Are dinosaurs the oldest mammals?
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
What evidence links birds to mammals in evolution?
No evidence links birds to mammals in evolution. However, there is evidence that birds evolved from dinosaurs. In fact, some biologists call birds "living dinosaurs".Birds have a similar hip structure to one class of dinosaurs, the ornithischians, but are actually more closely related to "lizard-hipped" or Saurischian dinosaurs, an order which includes the theropods such as Tyrannosaurus rex. It is now known from fossil evidence that some theropods had feathers, not only for warmth but also for display. They would have looked remarkably like birds, apart from the inability to fly.The lines that led to mammals and dinosaurs separated about 325 million years ago with actual mammals and dinosaurs appearing at roughly the same time about 235 million years ago. The first birds evolved from dinosaurs about 220 million years ago.
What was similar to both dinosaurs and birds?
Birds are more like dinosaurs to the extent that many scientists say that they are dinosaurs.
