The change over time that is the definition of evolution is quite well illustrated in the fossil record, especially at the level of higher taxa. The simplicity that becomes multicelled complexity is well written into the mineralization of the fossils left behind over the millions of years.

Evidence for continental drift?
The existence in the fossil record of the same land species on several continents. Since these animals are not seafaring then the continents must have been connected at one time. Also continental drift is supported by vast empirical evidence.
How is the fossil record like a jigsaw puzzle?
Because we have quite a lot of evidence of prehistoric life and we just need to put together what we have and know like a jigsaw to make a clear picture. However many pieces are still missing as fossilisation is quite rare and many species of life will not have been preserved. Pieces are also missing because we have not found all of the fossils on earth yet as we have not had the technology and time to yet. The fossil record is also like a jigsaw in the way that one little piece of evidence can just put everything together and make things much more clear.
Can you list three pieces of evidence that supports the idea that the dust bowl was the worst hard time?
List three pieces of evidence that support the idea that the Dust Bowl was “the worst hard time.”
What are 2 main pieces of evidence that prove wegner's theory?

What is two pieces of evidence that dry tea is a mixture and not a substance?
Dust and leaves
What are three pieces of evidence used to support the idea of Pangaea?
The three pieces of evidence used to support the idea of Pangea include the shape of the continents, fossil records, and geographical markers. Pangea was the single land mass which broken into numerous pieces to create the Earth as it is today.
What are the three pieces of evidence that supports continental drift theory?
Climate fossil and fossil climate
What are 4 pieces of evidence of evolution?
Part 1: Evidence from the Fossil Record Part 2: Evidence from Geographic Distribution of Living Species Part 3: Evidence from Homologous Structures and Vestigial Organs Part 4: Evidence from Embryology
What fossil evidence is considered an intermediate between reptiles and birds?
The oldest bird fossil Archaeopteryx is a transitional form between reptiles and birds and is cited as evidence Describe three additional pieces of evidence for this claim?
What are pieces of evidence that support the idea of Pangaea?
Continental Fit, Fossil Evidence and Sea floor Spreading. I just did this in science a month ago. :)
Is fossil record considered scientific theory?
Probably more in the line of many converging pieces of evidence in support of theory. Theory is explanation and fossils are just mineralized bones in the rock. which need and explanation. The fossil record supports the theory of evolution by natural selection and, some say, the theory of punctuated equilibrium.
What are the four pieces of evidence that scientists point to as proof of natural selection?
Among myriad others; fossil evidence, artificial selection, biogeographic distribution of organisms and molecular genetics.
What pieces of evidence Alfred wegener used to support his theory?
The pieces of evidence Alfred Wegener used to support his theory about continental drift were; Puzzle Fit, Fossil evidence from animals that were once on the same continent, geologic evidence like mountain chains that were connected and now split apart, and ice sheets. Thank you for reading this article and I hoped it answered your question!
Why do scientists believe evolution occurred?
Charles Darwin developed the Theory of Evolution by Natural Selection before most of the fossil evidence for the theory existed. He looked at the micro-evolution practised by pigeon breeders, the evidence on the Galapagos Islands and elsewhere, and realised that evolution was the only explanation that made sense. He saw that related species were to be found in close proximity, evidence of evolution from a single parent species, whereas a single act of Special Creation ought to have placed the species anywhere on the globe where the environment was suitable.The fossil record shows clear evidence of evolution over a period of more than a billion years. Certainly, at first, there were no transitional species among the many species that had been found, although scientists saw much that did confirm the Theory of Evolution. That has changed, because many transitional species have been found. A recently discovered 220-million year old fossil, Odontochelys semitestacea, is a new species of turtle that had a fully formed shell on its underside, but only a small partial shell on its back, extending from its backbone. As well as a partial shell, Odontochelys semitestaceaalso had ribs that had begun to widen, thus demonstrating that the fully developed shell of later turtles evolved from the ribs of earlier species. Tiktaalik roseae is the name of a newly discovered lobe-finned fossil fish from the late Devonian period, that is a transitional form to amphibians, with basic wrist bones and simple fingers, as well as the robust ribcage necessitated by existence out of water. Odontochelys semitestacea and Tiktaalik roseae are two more pieces in the jigsaw that shows conclusively how life on Earth evolved from earlier species.Scientists can now use DNA evidence from modern species to support the fossil record, as further evidence of evolution.
How does Darwin's theory of evolution explain microevolution but not macroevolution?
Those terms need to be done away with. There is no such division in the theory of evolution by natural selection, even in Darwin's time. There is evolution and speciation. One flows seamlessly into the other over time and we have myriad pieces of evidence supporting this.
What are the 6 pieces of evidence that prove the continents were once connected?
Shape, fossil animals and plants, magnetic field reversals, residual magnetic fields of rocks, subduction zones.
What makes evolution a therory?
Evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains much about the fact of evolution. That is what make a theory, explanation. Facts are useful, but uninteresting. Theories explain facts by gathering many convergent pieces of evidence and putting it into a logical and consistent whole.
