Does the extent of sexual dimorphism in a species affect the rate of evolution in that species?
Lauramay13
Perhaps, coupled with sexual selection. Take the elephant seal. The preference of females for large males to head the harems drove the evolution of larger and larger variance in the size of the males to the females and rather quickly.

You can alter human evolution?
I believe that yes you can alter human evolution not in the sense that you can change our very exsistence but in the sense that you could"ve postponed it. Such as the way we and other people interbreed some of the evolution of homo sapiens definitley formed that way but they were also already in exsistence and in competition with neanderthals. So yes I say you can alter it but no to that much of an extent.
What are the six adverb questions?
They are: When? Where? How? To What Extent? How Much? How Long?
Who proved evolution to be true?
Evolution as an idea has existed since ancient times. The first thinkers to propose that modern lifeforms evolved from earlier forms were Greek philosophers, like Anaximander and Empedocles, living centuries BCE. Naturally, they thought that the way life and the world presented themselves to them was evidence for their hypotheses. It wasn't until Charles Darwin that a comprehensive explanation for evolution was proposed, one that consisted of falsifiable hypotheses and that was supported by independently verifiable evidence to such an extent that it defeated alternative explanations in scope and accuracy. For more information, see links below.
Can you compare and contrast gradualism and punctuated equilibrium?
punctuated equilibria accounts for the gaps in the fossil record. Species evolve quickly during relatively short periods. Tiny changes in a species gradually add up to major changes over very long periods of time. Gradualism proposes that evolution occurs slowly but steadily. These periods of rapid change are separated by long periods of little or no change.
What determines the extent of resistance to a change of motion?
The extent of resistance to a change of motion is determined by an objects mass. The mass of the object is measured in kilograms.
Does the environment dictate only the direction and extent of evolution?
The environment is the ' natural selector ' of all variation. This is evolution.
What evidence of evolution can be found in the geographic distribution of living animals?
All organisms are adapted to their environment to a greater or lesser extent. If the abiotic and biotic factors within a habitat are capable of supporting a particular species in one geographic area, then one might assume that the same species would be found in a similar habitat in a similar geographic area, e.g. in Africa and South America. This is not the case. Plant and animal species are discontinuously distributed throughout the world
Can you stop crossing over to cease any kind of evolution?
Not to stop evolution, but you would be impeding variation within populations of sexually reproducing species by stooping crossing over. Only to an extent, though. One would still have to account for independent orientation of chromosomes and random fertilization. Then you have the driver of great variation to contend with; mutation.
Was Charles Darwin's contribution negative or positive?
A:To the extent that Charles Darwin helped us understand the mechanism for the evolution of species, his contribution was undoubtedly positive. The reaction of some conservative religious people to his Theory of Evolution by Natural Selection was a negative contribution that, for some people, has held back the understanding of science by a hundred years.
What are the factors that affect tha comprehension?
extent of vocabulary
What are three theories about the rate of evolution?
I am aware of the following notions regarding the rate of evolution:Gradualism, that the rate of evolution is more or less uniformly gradual.Punctuated equilibria, that evolution is gradual, but punctuated by rapid fluctuations in rate of progression.Saltationism, that new species can emerge instantaneously, from one generation to the next.Saltationism has, to a certain extent, been disproved as a pattern for evolution, along with gradualism, although saltational events may on occasion still occur, for instance in cases of polyploidy, chromosomal fusion, or radical changes in HOX genes.
Who is known for the theory of evolution by natural selection?
Charles Robert Darwin and to a lesser extent, Alfred Russel Wallace.
Does the sail design affect the speed of model sailboat?
Yes, to a huge extent
If evolution is real why are there still monkeys?
Evolution is the change in populations, not in individuals.Evolution is not a process in which species universally progress up a "ladder".Humans are not descended from any modern species of monkey; both monkeys and humans are descended from some long-extinct ancestor pre-dating both. Although this species, if it were transferred to today, would be considered a "monkey", it is not any living species of monkey.Evolution explains how humans developed from a primate ancestor, but not an extant species of monkey or ape. (Modern primates include: bonobos, chimpanzees, gorillas, baboons, macaques, lemurs, gibbons, and humans. None of these is a descendant of any other.)Speciation can occur by branching into two or more reproductively isolated populations (cladogenesis) or when a single population changes over time to such an extent that the later population is considered a different species (anagenesis).
How can an ecosystem be disrupted?
Ecosystem disruption can be defined as the affect on the environment where human subsistence has altered the face of the environment to the extent that survival of a species is threatened.
Does pollution affect pH balance?
AIr polution does affect pH in the oceans so it would in pools as wel to a very small extent.
To what extent should endangered species be protected?
An endangered species should be protected until they are no longer endangered. This means that the population should be stable and able to support itself.
