Biological evidence of continental drift

Theory of continental drift - in 1911, alfred wegener noticed that the continents appeared to once fit together like puzzle-pieces he also found evidence of identical plant and animal fossils on continents that were separated by oceans this evidence made wegener think about how this could. Evidence for continental drift what is continental drift in the early 20th century, german scientist alfred wegener proposed the continental drift theory, which argues that the continents drifted to their present locations over millions of years. Evidence of continental drift wegener's theory was extremely controversial and was not widely accepted by the scientific community for many years one of the main pieces of supporting evidence was the discovery of geological structures on different continents having closely related formation. The continental drift idea alfred wegener was an early 20th century german meteorologist wegener and his supporters collected a great deal of evidence for the continental drift hypothesis wegener found that this evidence was best explained if the continents had at one time been joined. Evidence of continental drift theory fossil plants and animals clue fossils of creatures and plants discovered on different continents helped to him push his case that the continents were once locked together before breaking up and drifting away some of the fossil evidence discovered on the.

Evidence for continental drift: the fit of the continents was a mystery to scientists for a long time if the continents were fixed in place, why did they look as maybe the ocean was lower and islands existed close enough together to allow animals to cross biological evidence for continental drift. Continental drift according to wegener, the continents drifted together to form the supercontinent pangaea (pan jee uh)pangaea means all lands as shown in figure 12, mountains and other features on the continents provided evidence for continental drift. Wegener's theory of continental drift has really been replaced by the theory of plate tectonics, which says that the earth's surface is covered by 8 major and about 42 smaller plates which move about the surface the driving force is convection currents in the earth's mantle.

According to continental drift theory, that´s how the world used to be, and where the world is heading, eventually the book weneger wrote was based on four different types of evidence with them, he wanted to prove that our continents as we know them now, had previously been a single one. Fossil evidence there are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined if continental drift had not occurred, the alternative explanations would be: the species evolved independently on separate continents - contradicting. Alfred wegener brought together several lines of evidence to support his theory of continental drift one is quite simple -- that the continents look like they could fit together, much like puzzle pieces that have drifted apart then, he noticed that when you put the continental puzzle pieces back together.

Evidence for continental drift earth looks so peaceful from space but looks can be deceiving now, if you were to put together the words continent and drift how would you relate them. There is strong supporting evidence in favour of the theory of continental drift such evidence includes similarities in rock types, fossils, flora and india provides a good illustrative example of the continental drift theory in paleontological terms, india is considered a southern land mass and is. An important piece of plate tectonic theory is the continental drift idea this was developed in the early part of the 20th century, mostly by a single scientist, alfred wegener his hypothesis states that continents move around on earth's surface and that they were once joined together as a single. Biological evidence fossils which are comparable with each other have been discovered in different continents these continental drift is also caused by plate tectonicssea floor spreading seafloor spreading is caused by two plates moving apart and thus the continents drift away from each other. Continental drift, geological theory that the relative positions of the continents on the earth's surface have changed considerably through geologic time as additional evidence wegener cited the unusual presence of coal deposits in the south polar regions, glacial features in present-day.

Evidence of continental as a meteorologist alfred wegener was well aware of some climatological puzzles, such as the some of the most telling climatological evidence comes from the continents of south america, africa, india, and australia all of these continents show evidence of past glaciation. Wegener put forward his theory of continental drift in 1912 stating that the continents were once joined together and were drifting apart dismissing the by 1922 wegener put forward his theory of a supercontinent using geological evidences wegener proposed that approximately 300 million years. Continental drift is a theory originally proposed by alfred wegener, who believed the continents were once one large continent finding fossils of the mesosaurus on the southern hemispheres of both continents is a further indication that the two continents were once together and later drifted apart.

Continental drift was a theory that explained how continents shift position on earth's surface set forth in 1912 by alfred wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents. Continental drift alfred wegener, in the first three decades of this century, and dutoit in the 1920s and 1930s gathered evidence that the continents had moved fit of the continents as far back as the voyages of exploration of the new world in the 16th and 17th centuries, as rudimentary maps.

  • In 1915, wegener proposed his continental drift theory he said that the continents floated atop the mantle-a heavier, denser layer of the good fit of the continents and the fossil and rock evidence did not provide enough proof for decades afterward, scientists still did not understand how massive.
  • Continental drift - evidence the evidence which gave rise to the theory of continental drift -- more correctly called plate tectonics -- includes the following: ► the coasts of the continents surrounding the atlantic ocean could, if the continents were moved closer, fit together like a jigsaw.
  • Data supporting continental drift theory fossil remains of similar organisms on widely disparate continents support the theories of continental wegener also found evidence of tropical plant fossils and coal deposits in the frigid arctic near the north pole, and also evidence of glaciation.

Throw some light on theory of continental drift provide some evidences to support it and its limitation wegener took inspiration from a map of continents to explain the earth's geologic history trained as a meteorologist, he was intrigued by the exact fit of africa's and south america's shorelines. Paleontological and biological evidences at the beginning of the century, the most influential paleontologists used to explain flora and fauna physical evidences supporting wegener's genial intuition were poor: he attempted to propose some mechanisms as the cause for continental drift. Theory of continental drift 124 likes 3 talking about this continental drift is the movement of the earth's continents creadores: alex y alberto as additional evidence wegener cited the unusual presence of coal deposits in the south polar regions, glacial features in present-day equatorial.
