What else can I help you with?
How did the hard shelled egg help reptiles adapt to life on land?
to protect them from pridators
Do reptiles lay eggs on land or in a nest?
Some reptiles lay egg in the nest and some reptiles lay egg on the land.
What did the different egg allow reptiles to be able to do?
Colonise land.
How is an amniotic egg important adaptation for reptiles?
The amniotic egg allows reptiles to reproduce on land, away from water.
Do reptiles hatch their eggs under water?
No. Reptiles must lay their eggs on land. If a reptile egg is submerged in water the embryo will drown.
The feature present in reptiles and absent in amphibians that freed reptiles from dependence on water for reproduction is?
The amniotic egg is the feature present in reptiles and absent in amphibians that freed reptiles from dependence on water for reproduction. The amniotic egg has protective membranes and allows reptile embryos to develop on land, reducing the need for water for reproduction.
How did the evolution of an amniotic egg help reptiles?
The amniotic egg allowed early reptiles to move away from waterside habitats and colonize dry regions. It allowed reproduction on land by preventing the embryo from drying out, so eggs could be laid away from the water.
What type of animal thought to have developed after the evolution of an egg that would not dry out on land?
Reptiles (I think)
What class of vertebrates are hatched from an egg on land?
There are two such classes: Reptilia (reptiles) and Aves (birds). Additionally, 5 species of monotremes, a group of mammals, are hatched from an egg on land.
What type of animal is thought to have developed after the evolution of an egg that would not dry out on land?
Reptiles are thought to have developed after the evolution of an amniotic egg, which allowed them to reproduce successfully on land without the risk of the egg drying out. This adaptation was a key factor in their ability to transition from an aquatic environment to a terrestrial one.
What was the most significant evolutionary change that allowed reptiles to colonize all the land was the evolution of?
Amniote egg
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.
