How does continental drift relate to evolution?
How does continental drift affect evolution? As continents broke apart from Pangaea, species got separated by seas and oceans and speciation occurred. This drove evolution by creating new species. Also, as the continents drift, they move into new climates.
How does the person explain the continental drift?
Continental drift describes one of the earliest ways geologists thought continents moved over time. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other.
Were there humans during continental drift?
No, no species that can be related to Humans existed during the Pangea period.
What evidence do we have for continental drift?
The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
How does continental drift affects the evolution and distribution of species?
The drifting apart of tectonic plates is the sort of event that could cause speciation. If the splitting of the land and of the species on it do coincide, the result is two species occupying complementary parts of a formerly continuous area that was occupied by their common ancestor.
How does plate activity influence evolution?
A planet with oceans, continents, and plate tectonics maximizes opportunities for speciation and natural selection, whereas a similar planet without plate tectonics provides fewer such opportunities. Plate tectonics exerts environmental pressures that drive evolution without being capable of extinguishing all life.
Where did humans evolve from continents?
Africa
The answer to the great question — “where did our species come from?” — has long been Africa. It was from somewhere in the African continent, most scientists believe, that modern humans evolved around 200,000 years ago before spreading across the world and becoming the dominant species we are today.
How are humans affected by plate tectonics?
Explanation: Plate tectonics can cause major earthquakes destroying large cities where people live. The Ocean formed by plate movements cause climate changes where warm water makes life easier and cold water currents make life harder. ( these are long term effects. )
How are fossils used by scientists to show that the theory of continental drift is correct?
One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.
How do continents fit together?
The continents fit together like pieces of a puzzle. Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions.
