Why did Archaeopteryx become extinct?
In a way no due to it just evolving into modern birds, it was in a kingdom aves (birds) but the exact Archaeopteryx is not a living thing anymore.
How is natural selection at work when a species becomes extinct?
Natural selection occurs when a certain environment favors a particular characteristic or trait over another. With this being said, when a species becomes extinct, this means that that species' particular set of characteristics or traits was not the most favorable for them to survive in that certain environment.
What is the difference between a species that is extinct and a species that is endangered?
A species that is extinct no longer exists anymore. Like the dinosaurs, for example. When a species is endangered, that means there are very few of their kind left on this planet.
What term describe development of new species and mass extinction?
Macroevolution
The development of a new species is called speciation.
What does a megladon tooth look like?
Exactly like the tooth of the great white shark, only much larger. Some found in Mesozoic deposits are 6 inches (15 cm) across the bottom. They are both species of the Genus Carcharodon. The Great White is Carcharodon carcharias, and the extinct Mesozoic monster was Carcharodon megalodon.

What are types of primitive bony fish?
If you are doing the cross word, the answer is Sturgeon - one of the oldest bony fish linking to fossils of primitive type. ;-)
What do scientists today rely on primarily to determine evoluutionary history?
Scientists rely primarily on the fossil record to determine evolutionary history. Another way of determination is examining the genetic record.
Was there a bird called Dodo and If so when did it become extinct?
It is not known exactly when the last dodo died, but it was believed to be sometime in the 1680s or 1690s. The dodo was not discovered on the Indian Ocean island of Mauritius until about the 1590s. It was a bird that had no fear of humans, having not encountered them before, so it was easy for sailors to catch and eat, even though most reports of the meat were that it was tough and sometimes unpalatable (usually due to cooking it for too long). It was a flightless bird, and quite heavy - around 20 kg, so it was not believed to be a fast-moving bird, although scientists differ in opinion on this. This meant it lacked the ability to escape terrestrial predators.
When humans settled permanently on Mauritius, they cleared native dodo habitat, destroying nesting grounds. They also introduced various new species, all of which were a threat to the dodo. Dogs and pigs killed the birds; cats and preyed on the young chicks; and Crab-eating Macaques were introduced from Asia - these ate the eggs of the dodo.
How many people have a lizard as a pet?

Why Yolk is absent in human egg?
A bird's egg is a self-contained unit. Everything the fetus needs to grow to birth weight is contained in the egg. The yolk provides the nutrients to bring that single-cell egg to birth stage. In humans, the nutrients are provided from the mother to the fetus by the umbilical cord.
What Australian rainforest animals are extinct?
There are many animals that are considered extinct from Australia. Some of these include: Thylacine, numbat, some species of bandicoot, and the Australian sea lion.
How many native Australian animals are extinct?
Australia has one of the world's worst records for extinction of native animals. This is largely due to the proliferation of introduced species, particularly feral cats, dogs, rabbits, cane toads and foxes.
Two of the better-known extinct species include:
- Tasmanian tiger (Thylacine)
- Lesser Bilby
A more complete list of extinct native Australian species can be found at the related link. This includes mammals, birds, reptiles, amphibians and insects.
