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.
Do reptiles and birds have similar life cycles?
To some degree. Both birds and reptiles reproduce sexually and have offspring that resemble their parents. All birds and most reptiles lay eggs. One key difference is that reptiles are born largely able to fend for themselves while birds are fairly helpless and need their parents' care. The only reptiles that provide parental care are crocodiles and alligators, which help their young hatch and protect them from predators, but do not provide food.
What does evolve means?
It means came into being over time by the processes of evolution, as set out by Charles Darwin.
What animal group did scientists put dinosaurs into?
That would be easy. Dinosaurs are in a group of Reptiles called Archosaurs which also includes birds,Crocodile,Alligators,Pterosaurs,and their possible ancestors- Thecodonts.
Did amphibians and mammals descend from reptiles?
Reptiles evolved from a group of reptiliomorph amphibians in the Carboniferous period. Mammals evolved from a groupof synapsidreptiles in the Jurassic period.
Did dinosaurs evolve into reptiles?
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
How do vertebrates evolve?
fish- amphibians- reptiles- birds -mammals
How did birds evolve 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.
Which type of critter did birds and mammals evolve from?
Birds and mammals both evolved from reptiles.
What did the lizard evolve into?
It is believed that snakes evolved from lizards. Lizards are an existing group of reptiles, of course, so did not 'evolve into' anything else--they are still here. While mammals and birds evolved from reptiles, they did not evolve from lizards.
Did birds evolve from lizards?
No, birds didn't evolve from lizards, but they did evolve from dinosaurs, a different group of reptiles. Dinosaurs are different from lizards especially because of their hip structure. Birds descended from a group of dinosaurs known as theropods (bipedal carnivores)
Did underwater dinosaurs evolve into crocodiles?
what an interesting topic! Birds and reptiles are the living descendantsof the dinosaurs that survived the meteorite-triggered mass extinction that killed off most of the species living 66 million years ago. And of all reptiles, crocodiles are the most closely related to birds.
Do snakes evolve from reptiles?
They ARE reptiles.
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.
Could ancient reptiles fly?
There were several types of ancient reptiles that flew. Most famously the pterosaurs such as pterodactyl (Pterodactylus) were the 1st vertibrates to evolve flight.Also it is quite likely that some species of the Dromaeosauridae family of theropod dinosaurs flew. They were later to evolve into birds. Infact the simularity between Dromaeosauride species and birds have led some scientist to argue for reclassification to birds.
Do birds eat reptiles?
There are certain birds that eat reptiles.
Are birds and reptiles amphibians?
No. Birds and reptiles are separate from amphibians.
