What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
Why do scientists combine evidence from fossil fuels body structures and early development and DNA and protein?
Scientists want to determine the evolutionary relationships among different species.
How do scientists determine the living relatives of a fossil?
They look for patterns in the morphology of the organisms. This science of pattern recognition between species is called phylogeny.
What two major developments helped scientists explain the fossil record?
The principle of fossil succession and the theory of evolution have helped scientists explain the fossil record.
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.
How scientists estimate the age in years of a fossil?
Scientists can use carbon dating to determine the age of a fossil.
How is the sex of an individual determined?
Scientists do not determine the sex of a fetus. Science does, but scientists do not.
How do scientists determine age?
by seeing what levels the fossil go to
What tool can help scientists to determine ancient species became extinct?
fossil record
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
Scientists determine evolutionary relationships between animal phyla using evidence from the?
Fossil record
What do scientists today rely on primarily to determine evoluutionary history?
Scientists rely primarily on the fossil record to determine evolutionary history. Another way of determination is examining the genetic record.
Why do scientists combine evidence from fossil fuels body structures and early development and DNA and protein?
Scientists want to determine the evolutionary relationships among different species.
How the age of plant and animal fossils is determined?
The age of a plant or animal in a fossil is determined by radiocarbon dating. This means scientists measure the amount of a special type of carbon in the fossil, to determine the date.
How do scientists determine the living relatives of a fossil?
They look for patterns in the morphology of the organisms. This science of pattern recognition between species is called phylogeny.
What evidence would a scientists use to determine the absolute age of a fossil found in sedimentary rock?
The Igneous intrusions and extrusions near sedimentary layers.
What two major developments helped scientists explain the fossil record?
The principle of fossil succession and the theory of evolution have helped scientists explain the fossil record.
