What would happen if there was zero variation between all of the organisms on earth?
Evolution cannot occur.
The process by which modern organisms have descended from ancient organisms is called?
The process by which modern organisms have descended from ancient organisms is called evolution.
What is the smallest group of organisms in which evolution can take place?
The smallest group of organisms wherein evolution can take place is a population. This is because all methods of evolution require chromosomes from more than one organism.
What is the smallest level on which evolution can occur?
Natural selection acts upon the individual organism, whilst evolution occurs at the population level. The environment selects for organisms best adapted for highest survival and reproductive success. Natural selection requires three key things - variation, inheritable traits, and differential survival/reproduction. Species will produce more offspring than the environment can support(carrying capacity), and the population tends to be fairly stable until resources are limited. A struggle for existence is created, and natural selection ensures that weaker traits die out while stronger traits live on. Organisms show variation in characteristics, and that variation is heritable. Survival depends on inherited traits, and unequal survival/reproduction leads to adaptation and evolution. Therefore, while the individual organism can adapt, the population is what actually evolves.
What statement is best supported by the theory of evolution?
Simple statement I often use to illustrate the definition of the theory of evolution by natural selection proceeded by the definition of evolution itself. Evolution is the change in allele frequency over time in a population of organisms. Natural selection is the nonrandom survival and reproductive success of randomly varying replicating organisms.
How are organisms related to evolution?
Organisms are required for evolution to occur. Evolution is defined as something that happens when organisms reproduce.
Does evolution continue to occur in organisms today?
Absolutely. Evolution isn't an historical process; it is on-going as long as there is life.
Define evolution at the population level?
That is the only level where evolution happens.Evolution is the change in allele frequencies over time in a population of organisms.
What would happen if there was zero variation between all of the organisms on earth?
Evolution cannot occur.
In the photosynthesis process what trophic level occur?
Photosynthetic organisms make up the producer trophic level.
How can you say that evolution is going on in this era?
Evolution is the change in allele frequency over time in a population of organisms. This is observable and observed at the molecular level in this era.
What is a cure for evolution?
One word: extinction. As long as life exists, organisms will reproduce with variation - which means per definition that evolution will occur. The only way for evolution to stop happening is for life to cease existing.
What happens to the number of organisms in each classification levels as you move from the kingdom level to each of the next levels?
evolution
What level does micro evolution take place?
Where all evolution takes place initially, and some say totally. The population. Microevolution is just this; Evolution is the change in allele frequency over time in a population of organisms. Macroevolution is that change magnified, some say, at the taxa level.
Is spontaneous generation the same as the current understanding of evolution?
No. Evolution explains how and why organisms change over time. It makes no difference to evolution how organisms are generated.
What is the change of organisms over time is known as?
Evolution.
Generally evolution by natural selection occurs quite slowly over?
Evolution through natural selection occurs slowly over millions of years. It has been hypothesized that evolution is the result of positive mutations that occur in a community of organisms that help them survive better. Evolution is essentially descent with modification.
