o Anatomical evidence: (structures of organisms) fossil evidence, homologous structures. Fossils reveal anatomical structures of past organisms and their relationships with living organisms. Homologous structures are structures found in different species that have similar form or configuration due to divergent evolution (common ancestor). The greater the amount of homology between two species, the more closely related they are. Ex) whale cat, gorilla, bat forelimbs(different functions but same bone structures)…

1. The fossil record provides an incomplete chronicle of evolutionary change because the fossil records favors species that existed for a long time, were abundant and wide spread in certain kinds of environment and had hard shells.…
Brain Size: Neanderthal people had a brain volume of about 1200 to 1800 cubic centimeters, equal to and even larger than modern human brains. Neanderthal skull reconstructions provide further evidence that they were a separate species to modern humans. Distinctive Neanderthal skull features were established in early infancy. Physical features in skull development, such as the Neanderthal’s receding chin and low, sloping forehead were fixed by the age of two years. Their hyoid bones, involved in speech, were basically identical to humans.…
In addition to this information science uses geological and fossil records to explain the changes and diversity that have happened between species over time,through the concepts of natural selection. Scientists believe each fossil is a piece of evidence about the way species adapted and the changes that took place over a period of time.…
Paleontology - Fossils provide a record over time of how living things have evolved. Fossils that are considered transitional fossils are those that have feature that make them an immediate form between organisms. Provide more evidence for change. Eg: Seen ferns have both features of ferns and gymnosperms.…

There are some incredibly specific items that need to be present in order for fossils to be procured, and they are only found in water, caves, or volcanoes. There is also a geological an scale, there needs to be dating, relative and absolute, by finding this fossils you now possess a better view of the times and are able to reconstruct ancient environments, which include climate and habitat reconstruction. Water needs to be present including sand, generally these are found around or in a lake, then there are caves, and volcanoes are an area because of the ash are the conditions and places for fossilization.…
Northeastern Illinois has a great deal of geological history hidden beneath the surface. If you just take a trip to the Larson Quarry or even Pit 11 you can find some interesting rock formations as well as fossils in them. But, if you cannot get to these areas, this paper can tell you what you can find in 5 different locations in Northeastern Illinois. We will be looking at Larson Quarry, Thornton Quarry, Mazon River, Pit 11, and the Glacial Drift which is at Palos Hills and throughout the surface of the Chicago area).…
Spearheaded by the Germans discovery of the skullcap and limbs, archaeologists gather information, make inferences, and use their imaginations to construct how things use to be. The conditions of the fossils let us know the kinds of conditions people/animals lived in. This can be problematic because for example, Neanderthal bones and deer bones were mixed together with some of the same marks. An archaeologist could have mixed up the bones and given the Neanderthal a characteristic of life that isn’t accurate to them. This could be the case for any fossil that isn’t easily identifiable and archaeologists have to use their “imaginations.”…
