The ultimate allopatric ( geographic ) speciation. If you had a population of quite similar organisms in a area that split the population into two or more populations when continental drift occurred you would have different mutations and changing environments putting selective pressure on two or more populations now.

What idea did Darwin add to the theory of evolution that Lamarck did not have?
Darwin introduced the concept of natural selection to the theory of evolution, which posits that individuals with favorable traits are more likely to survive and reproduce, passing those traits to future generations. In contrast, Lamarck's theory emphasized the idea of inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to offspring. Darwin's focus on variation and survival in relation to environmental pressures marked a significant shift in understanding evolutionary processes.
What ideas were changing in the scientific communiyy at the time of Darwin's travel?
During Darwin's travels in the early to mid-19th century, the scientific community was witnessing a shift from static views of species to concepts of evolution and natural selection. The prevailing belief was largely influenced by religious doctrine, which held that species were immutable and created as they were. However, observations from geology, comparative anatomy, and paleontology began to suggest that species could change over time. This emerging understanding laid the groundwork for Darwin's theory of evolution, challenging established beliefs and paving the way for modern biology.
How did Darwin's ideas affect classification system?
Darwin's ideas fundamentally transformed the classification system by introducing the concept of evolutionary relationships among species. His theory of natural selection emphasized common descent, leading to classifications based on phylogenetic relationships rather than merely morphological similarities. This shift encouraged the use of evolutionary trees, or cladograms, to represent the connections between species, ultimately laying the groundwork for modern taxonomy and the understanding of biodiversity.
How did Darwin and Lamarck differ in their thinking about change in species?
Darwin and Lamarck had fundamentally different views on how species change over time. Lamarck proposed that organisms could acquire traits during their lifetime and pass those traits to their offspring, a process known as inheritance of acquired characteristics. In contrast, Darwin introduced the theory of natural selection, suggesting that species evolve through the differential survival and reproduction of individuals based on heritable traits that confer advantages in a given environment. This marked a significant shift toward understanding evolution as a gradual process driven by natural mechanisms rather than intentional adaptations.
Why is the evolution of a coelom significant in the complexity of animals?
Having a coelom allows and animal's system to be complex because the internal organs can shift around and develop independently of the body wall, creating more physiological and evolutionary flexibility.
How do continental shifts change the rainforest?
The amazon basin was created by a continental shift!
How did Darwin's theory of evolution affect society?
In Darwin's mind his theory took away the need for a god. Darwin's theory of evolution challenged both the Religious and the science communities at that time. He was challenged by Alfred Wallace who had individually come up with the idea so Darwin published his book (Origin of Species...) first.
How does red-shift support the steady state theory?
Red shift does not support the steady state theory.
How is plate tectonics related to the theory of continental drift?
Plate tectonics is the scientific theory that explains how the Earth's lithosphere is divided into large, rigid plates that move and interact with each other. This theory is closely related to the theory of continental drift, which suggests that the Earth's continents were once connected as a single landmass called Pangaea and have since drifted apart to their current positions. Plate tectonics provides the mechanism for how this continental drift occurs, as the movement of the plates causes the continents to shift and change position over time.
Which kind of mutation has greater potential to affect the evolution of a population Explain?
A frame-shift mutation has greater potential to affect the evolution of a population because it can alter the entire reading frame of a gene, leading to a non-functional protein. This can result in significant changes to an organism's phenotype, potentially affecting its survival and reproduction, and thereby influencing the population's evolution.
What causes continental shift and drift?
Natural Disasters.
How do you use paradigm shift in a sentence?
The archaeological dig brought about a paradigm shift in my understanding of evolution.
What did the theory of continental drift not explain?
The theory of continental drift, proposed by Alfred Wegener, did not adequately explain the mechanism behind the movement of continents. It lacked a convincing process to account for how continents could shift across the Earth's surface, as Wegener suggested they moved through oceanic crust. Additionally, the theory could not explain the geological features and phenomena associated with plate tectonics, such as earthquakes and volcanic activity, which were later clarified by the theory of plate tectonics.
What is the cause and effect of Darwin's theory?
The cause of Darwin's theory of evolution was his observations of natural variation and adaptation in species during his travels, particularly in the Galapagos Islands. The effect of his theory was a paradigm shift in biology, leading to a better understanding of how species change over time through the process of natural selection.
Was the theory of super continent originally accepted by scientist?
When German meteorologist Alfred Wegener first published his theory on Pangea (super continent) he was widely ridiculed for it. Some of the reaction to his theory on continental shift and a super continent was actually quite hostile. The idea was first put forward in 1912 but it wasn't until the 1950's that his idea was really rethought. By then evidence of continental drift was starting to support his ideas.
Where is the shift solenoid for a 1992 Lincoln Continental located?
shift solenoid, never heard of that. ill check that out and get back to you.
When the theory that the sun goes around the earth was replaced with the theory that earth goes around the Sun this was an example of?
When the theory that the Sun goes around the Earth was replaced with the theory that the Earth goes around the Sun, it was called a paradigm shift.
