new layer of the fossils
Existing species can be seen in the wild or in captivity. You can't say the same for extinct species. An extinct species has no living members.
A skull is considered a type of body fossil, which is formed from the remains of an organism. Body fossils typically include hard parts such as bones and teeth, and the skull represents the preserved structure of an animal's head. These fossils provide valuable insights into the anatomy, behavior, and evolution of the species they represent.
Carthage used a species of elephant called the North African Elephant (Loxodonta africana pharaoensis) as war elephants against the Romans in the Punic Wars. They were a bit smaller than the existing African bush elephants, which made them a little bit faster. They were also used as war elephants by the Ancient Egyptians against the Seleucid Empire. The North African Elephant is now extinct and has been since around 100AD. Fossils of this elephant are rare to find, we have mostly learnt of their existence through Roman writings and several archaeologically recovered Roman bronze statues of them.
For one thing it may eat the other species. For example the introduction of the house cat in to the wild in western Australia led to the demise of many small land welling creatures, to the point where cats are now seen out at sea hunting for fish. It can also starve the existing species in an area out by eating that which the established species needs to survive. The cane toad was introduced into Australia and is now causing a problem with animals that eat or bite ir as they are poisonous.
There are about 15 species of ancient plants classified in the plant genus Equisetum. They are generally considered living fossils and reproduce via spores instead of seeds. The stems are hollow and the leaves are much reduced and often look like part of the stems. The height of the plants vary among the species from about 6 to 8 inches to more than 30 feet.
The more recent rock layers will contain fossils that are more similar to current species because of evolution. The older the fossils, the more evolutionary changes will exist between them and current species which accounts for the greater differences.
The principle of fossil succession states that fossils found in younger layers of rock tend to be more similar to current species, while fossils in older layers differ more. This is because newer fossils represent species that have evolved and survived to the present day, while older fossils may belong to species that have become extinct. This pattern helps scientists understand the evolution and biodiversity of life on Earth.
If there was no change in species over time, then all fossils of that species would be identical.
They say that there were more animals before that went extinct, but the animals that are here today survived and are still here.
Fossils' existence confirms that species are not fixed but can evolve into other species over time
Yes, some species of moss produce reproductive structures known as sporophytes, which can resemble cones. These structures contain spores that allow the moss to reproduce.
Fossils are used to show changes because they are permanent. These fossils are also old and show evolutionary changes in species alive today.
Biological diversity
Biogeography is the study of the distribution of species (biology) spatially (geography) and temporally (history). Biogeography aims to reveal where organisms live, at what abundance, and why they are or are no) found in a certain geographical area. Biogeography does not support the theory of evolution any more then when (history) you (biology) moved into your house (geography).
