Yes
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
Fish - amphibians - reptiles; and from the reptiles birds and mammals.
Both mammals and birds are descended from reptiles.
Birds and mammals both evolved from reptiles.
But they did. Specifically, birds evolved from a subgroup of dinosaurs (which were reptiles) known as theropods. There is a lot of fossil and anatomical evidence for this.
Because they can generate their own body heat - reptiles cannot and need a warm environment
birds evolved from reptiles.
Scientists believe birds evolved from dinosaurs because of several pieces of evidence, such as shared skeletal features, fossil records of "transitional" bird-like dinosaurs, and genetic similarities. These connections suggest that birds are the descendants of a group of small theropod dinosaurs.
Birds evolved from small reptiles that lived during the age of dinosaurs, but not from the dinosaurs themselves.
Amphibians, then reptiles, birds, and finally mammals!
No. Lizards evolved from a separate group of reptiles and, as far as reptiles go, are not closely related to dinosaurs. The modern "evolved form" of the dinosaurs is actually the 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.
