Anatomical Homology is the study of how different species can have similar structures. Biogeography is the study of how animals and plants are distributed throughout the world. Embryology is the branch of biology that deals with the formation, early growth, and development of living organisms. It also helps us understand how far back in time each species has been around.

Our Earth has been around for approximately 4. Rocks are full of evidence that life formed on Earth nearly four billion years ago. We find fossils such as sea shells, imprints of plants and animals, and burrows from worms that crawled through the soil long before man existed. In the high Himalayan peaks we find fossils of life forms that lived in oceans long ago.
Examining the Fossil Record
Concepts carry over from one lab to the next and are reinforced so that at the end of the semester, the students have experience at interpreting the rock record and an understanding of how the process of science works. Request permission to reuse content from this title. All rights reserved.
Learn something new every day More Info The fossil record is the collective accumulation of the remains of organisms that have been preserved, particularly in rock, all over the world, and which are generally at least 10, years old. When viewed as a whole, it can provide interesting information about the evolution of life on Earth. Scientists consider the remains they have found to be extremely precious and apply what they learn from them into multiple disciplines. They routinely try to fill in gaps in the record to have a better understanding of the world.
