5 factors that lead to the formation of a new species?
(i) Absence of gene flow (ii) accumulation of different variations (iii)natural selection (iv) genetic drift (v)reproductive isolation.
What conditions are necessary for populations to remain in hardy Weinberg equilibrium?
Mutation cannot occur
What are the conditions that must be met for a population to stay in genetic equilibrium?
Hardy-Weinberg equlibrium is reached and maintained under the following conditions:Large populationRandom matingNo mutationNo natural selectionNo emigration/immigration

The New Statesman - 1987 Natural Selection 3-5 is rated/received certificates of: UK:15 (video rating) (2000)
What causes the allele frequencies to changes?
1. Mutation 2. Migration (Gene Flow): both immigration and emigration. 3. Genetic Drift 4. Sexual Selection (Non-random mating) 5. Natural Selection: those most fit survive to pass on their genes to the next generation.
What is the mechanism that allows organisms to evolve?
1) Natural Selection 2) Climate changes 3) Geographical events 4) Radiations of organism into new habitats 5) Changes in ecosystem 6) Changes in continental position Above are mechanisms of selection, the environment, basically. Mechanisms of evolution are; mutation, gene flow. genetic drift and most importantly for adaptive changes, natural selection

The Philosophiæ Naturalis Principia Mathematica, which is Latin for "mathematical principles of natural philosophy", often Principia or Principia Mathematica for short, is a three-volume work by Isaac Newton first published on 5 July 1687.
What are the 5 factors that influence genetic variability in a population?
Population Size, Mate Selection, Gene flow between Populations, Mutations and Natural Selection Hope that helps

What are the 5 ways a population can evolve?
A population will most likely evolve when there is a small population, mutations exists, natural selection may take place, nonrandom mating occurs, and/or gene flow may occur. Sexual selection, genetic drift, Gene flow, Mutation, and natural selection are five ways a population can evolve. Sexual selection is natural selection arising through preference by one sex for certain characteristics in individuals of the other sex. Genetic drift is variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce. Gene flow is the transfer of alleles or genes from one population to another. Mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
How can differences in each of 5 senses drive natural selection in a chimpanzee?
The chimps taste for fruit drove the selection of individuals that were tending towards trichromatic vision. This allowed them to distinguish the ripest fruit, thus the best nutritionally, with their color vision. Thus this drove selection for these individuals as this train was reproductively successful.
The five principle evolutionary forces are?
I know of 5: natural selection mutation genetic drift gene flow (migration) and im pretty sure nonrandom dating is one
Where did Charles Darwin come up with the idea?
Darwin left on his trip in 1831 on HMS Beagle. The trip took 5 years. He came up with his idea of natural selection on the trip.
