They look for patterns in the morphology of the organisms. This science of pattern recognition between species is called phylogeny.

How do fossils help scientists learn what happin in the past?
Scientists can learn from a fossil of animal by its age, diet, and physical characteristics, depending on the condition of the fossil. For example, scientists would not be able to tell of a hominid was a new species or not if a few bones were missing, because of the fact that they could determine different or similar traits than other species of hominid.
Is there any way scientists can determine what percentage of carbon dioxide in the atmosphere is from the burning of fossil fuels compared to other sources of carbon dioxide such as respiration or for?
Yes, scientists can tell the difference. Carbon dioxide (CO2) released from the burning of long-buried fossil fuels contains carbon of different isotopic ratios to those of living plants. So we can distinguish between natural and man-made CO2.
What are the common names of ginkgo biloba?
The genus and species name of the tree that produces this leaf, is: Ginkgo biloba.Related Information:It is an interesting species and is called a living fossil. This is due to the fact that none of its close relatives are represented in the fossil record after the Pliocene epoch (ca 5.3 - 2.6 million years ago). This tree, alone of all its relatives, survives to the present.
What is the living fossil among the pteridophytes?
equisetum
What is the remains of a once-living organism?
Fossil
What is a relive of the dinosaur?
The closest living relatives of the dinosaurs are birds. In fact, scientists consider them true dinosaurs. The second closest living relatives of the dinosaurs are crocodillians.
Are paleontologists scientists?
Yes, they are. They study the fossils of thing that were once living (they can't still be living otherwise they couldn't be a fossil).
What is a record of past living things called?
Fossil records is the information gathered about living things that are now extinct. Scientists use information gathered on and around fossils to determine things like size, mating rituals, and behavior of extinct animals.

How did the scientists verify the remains of the romanovs to be authentic?
Scientists took DNA samples from the remains of the Romanov family and compared them to DNA samples from known living relatives to know they were authentic.

What is a living fossil fuel?
a living fossil fuel.
What are humans' farthest relatives?
Humans' farthest relatives are believed to be other primates, such as gorillas, orangutans, and chimpanzees. These species share a common ancestor with humans, although the evolutionary paths diverged millions of years ago.
What have scientists from fossil records?
Fossils were of grear interest to early scientists because there: * appered to be of unusual, unknown organisms that were no longer living * are no fossils of most living species * buried very deep within rock more than 1km
What animal did scientists believe were most similar to dinosaurs?
The birds, having evolved from dinosaurs, are their closest living relatives. Crocodilians are the second closest relative of dinosaurs.
What is the term for the remain of a once-living organism?
fossil
Why do scientists have a problem reconstructing dinosaurs?
There are a number of reasons that feed into this. 1) Partial Skeletons: In many cases, scientists only find partial dinosaur skeletons, that are missing key bones or fragments. In other cases, scientists have a large number of different creatures that decayed together and have interlocking bones, such as in the La Brea Tar Pits. In those cases it is difficult to determine which bones belong to which creatures, especially if there are very few other examples of similar creatures. Another issue is that the bones are usually preserved in a crumpled mess. They are are not arranged nicely in sequence. 2) No Living Relatives: Scientists can analyse skeletons based on similar living relatives, such how the shape of the leg determines walking patterns or how the musculature fits over the bones. However, in the case of dinosaurs, the closest living relatives are birds, who have a very different anatomy. As a result, it takes a while for scientists to come to a consensus as to how the animal held itself and moved. 3) Unclear If a New Species: Dinosaurs are not discovered with name tags, so it is not immediately obvious if a fossil being unearthed is known or unknown. As a result, a scientist must be cautious before assuming that this is a creature that is already discovered and make sure not to hastily assemble the creature, if it is a new species, in the model or shape of a known species.
