Two conditions necessary for fossils to form?
well in your body there are made up of fossils as fossils are formed in hot places and your body is very warm
What are two types of evidence that suggest that evolution has occurred?
The two types are Dna, and fossils
What two types of dating techniques are used in dating fossils?
Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave fossils. Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating, which provides absolute dates that are accurate to within 0.5%, but more often paleontologists have to rely on relative dating by solving the "jigsaw puzzles" of biostratigraphy.Classifying ancient organisms is also difficult, as many do not fit well into the Linnean taxonomy that is commonly used for classifying living organisms, and paleontologists more often use cladistics to draw up evolutionary "family trees". The final quarter of the 20th century saw the development of molecular phylogenetics, which investigates how closely organisms are related by measuring how similar the DNA is in their genomes. Molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend.
What are two common fossils are found in Pennsylvania?
The Trilobite.
What are two common tools that scientists use when cleaning fossils?
bacon
What Two things that paleontologists can learn from fossils?
one that they can learn there definitely was life before and 2 that our ancestors developed to form us humans
Why is it important for paleontologists be experts in both anatomy and geology?
Paleontologists need to have a working knowledge of geology to recognise not only which rock is best to search for fossils but also to recognise fossils from the surrounding rock. They need to have a working knowledge of anatomy (biology) to recognise what part of the animal or plant they are looking at.
What two things can be made into fossils?
Plants and animals
How do Paleontologists use the remains of the Trilobites?
Paleontologists use the fossils of different aged trilobites to identify the age of rock formations and fossils in other locations. Similar trilobites found in British Columbia as found in Asia would indicate the rock was nearly the same age from both sites. May also mean that the two locations were once close together, but moved away due to plate tectonics.
What is a scientist called who studies rocks and fossils?
Strictly speaking these are two differing types of scientists. Petrologists study rocks and paleontologists study fossils. However both these disciplines are covered in the broader training of a geologist.
What two ways paleontologists age of fossils?
Paleontologists age fossils primarily through relative dating and radiometric dating. Relative dating involves determining the age of a fossil based on its position in sedimentary rock layers, using the principle of superposition, where younger layers are deposited on top of older ones. Radiometric dating, on the other hand, measures the decay of radioactive isotopes within the fossils or surrounding rocks, providing a more precise numerical age. Together, these methods help build a timeline of the Earth's biological history.
What are two things that scientists learn from the fossils record?
The fossil record provides evidence about the history of life and past environment on earth. The fossil record also shows that different groups of organism have changed over time.
What two important things people can learn by studying history?
Two important things people can learn from studying history is the grest triumphs of the past and the things that happened long ago that to not repeat again.
What two things did civilization learn in the Middle East?
agriculture, and writing
What are two kinds of fossils?
Two kinds of fossils are body fossils, which preserve the actual remains or impressions of an ancient organism, and trace fossils, which are indirect evidence of an organism's activity, such as footprints or burrows.
What are Two most common types of fossils?
There are a variety of types of fossils. These include cast fossils, mold fossils, petrified wood, as well as fossil fuels.
What is the principal of paleontological identity?
The Principle of Paleontological Identity is the theory that the layers of sedimentary rocks around the world can be dated by the fossils which they contain. Based on this theory, two layers having the same fossils are regarded as having the same age. This principle is based on the existence of stratigraphic fossils. It is taken in theory to make it possible to correlate sedimentary sequences in distant areas from each other.
