Why do scientists believe that birds evolved from dinosaurs?
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.
What came before the fish amphibians reptiles and dinosaurs?
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
What family is the lizard from?
lizards are a group of reptiles that evolved from amphibians.
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.
Where do scientists believe plants evolved?
Scientists believe that plants evolved on land from green algae, specifically from a group called charophytes. This transition from water to land occurred around 450 million years ago during the Ordovician period.
Which group of vertebrates evolved after fish?
Amphibians, then reptiles, birds, and finally mammals!
What group evolved from the amphibians with the development of the amniotic egg?
reptiles
Scientists who argue that modren humans evolved from asingle population believe that humans came from the continent?
They believe that the evidence point to this group of people living in Africa.
Why do scientists classify fish amphibians reptilesbirdsand mammals together in one group?
Fish, reptiles, amphibians, birds, and mammals are all vertebrates. They all have a backbone and internal bones.
Why do scientists classify fish amphibians birds and mammals all in the same group?
All are vertebrates - all have a spinal column.
What is a Evolved from lobe-fined fish?
Evolved from lobe-finned fish, tetrapods are a group of vertebrates that includes amphibians, reptiles, birds, and mammals. One of the key characteristics that distinguish them is having limbs with digits, which evolved from the lobed fins of their fish ancestors. This transition from water to land was a crucial step in the evolutionary history of vertebrates.
What group of animals is thought to have left the ocean to become the first amphibians?
Devonian, lobe-finned fish had evolved into air-breathing amphibians with strong legs, yet retained a fish-like head and tail.
