Forest X has some of the country's oldest trees and has never been logged. Forest Y was
agasfer [191]

Given what we know, we can confirm that of the two forests mentioned, the old forest that is named forest X will have a greater level of biodiversity.

<h3>Why is forest X more diverse?</h3>
  • Forest X is older than Forest Y.
  • Therefore forest X has gone through more development phases.
  • This allowed more opportunities for species to adapt to the forest.

Therefore, given that forest X is older it has had more time to go through each phase of the development of the forest and prompt the rise of many different species that may now call it home. Through this, we can confirm that age is an indicator of the biodiversity and health of a forest.

How do fossils provide evidence to support the theory of the evolution of earth?
Zigmanuir [339]

Answer:

Fossils provide direct evidence of evolution. They show the changes of animals from ancient organisms to present form. Fossils are the preserved remains of earth layers. There are 4 types of fossils-

Original fossils that are not very old.  e.g. teeth, skeleton, shells.

Frozen fossils

less permanent fossils

casts, molds,  and prints - wings, skin, leaves, etc.

The fossils show the adaptive radiation in horses, humans. The transition fossils form the connecting link between different groups such as fish and amphibians, reptiles and birds, etc.  

e.g. Archeopteryx is the connecting link between the reptiles and birds.

The modern horse Equus have several ancestor species, we came to know from the fossil records.

The fossil record shows the evolution of humans and their ancestors.
