Which can adapt to change alleles offspring individual or populations?
It is populations which adapt. Alleles are passed on or not, offspring and individuals survive or not.
What is the process by which the best suited individuals survive in their environment?
The answer of that qeustion is natural selection of which animals produce offspring.
How can genetic material variation help some offspring survive?
Because on very, very rare occasions the variation may be helpful
What are Darwin's four postulates?
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
What advantages does sexual reproduction provide for sponges?
Sexual reproduction means there is much greater scope for genetic variation of offspring. Variation is good for any species as it is this variation that allows for adaption e.g. the variation might provide some individuals with resistance to a new disease that affects the species, hence those individuals survive and thrive.
How can variation lead to survival in the changing environment?
The survival of a species relies on at least some individuals producing offspring. The organisms best adapted to their environment are the most likely to produce offspring. These are the organisms that have favorable characteristics, enhancing their ability to survive and reproduce.Their offspring will inherit these favorable characteristics. Over several generations, individuals with favorable characteristics will become the most common. In contrast, those with less favorable characteristics will be more likely to die before they get a chance to reproduce and so will become less common.For clear: We can say that favorable characteristics are ‘selected’. Variation in a species is particularly important if environmental conditions change. Some individuals will have characteristics that are favorable, allowing the species to survive the change.
Which can adapt to change alleles offspring individual or populations?
It is populations which adapt. Alleles are passed on or not, offspring and individuals survive or not.
What are the 4 key principles of natural selection?
1. Overproduction - more offspring are born than survive 2. Genetic Variation - there is variation in the population 3. Struggle to Survive - organisms with suitable variations will survive and reproduce 4. Differential Reproduction - suitable variations are passed on to offspring
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do?
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals is called natural selection. This is part of Darwin's theory.
What is the process by which the best suited individuals survive in their environment?
The answer of that qeustion is natural selection of which animals produce offspring.
How can genetic material variation help some offspring survive?
Because on very, very rare occasions the variation may be helpful
What are the four major points of the theory of natural selection?
1. Overproduction - more offspring are born than survive 2. Genetic Variation - there is variation in the population 3. Struggle to Survive - organisms with suitable variations will survive and reproduce 4. Differential Reproduction - suitable variations are passed on to offspring
What are the principles of the theory of evolution?
1. Organisms share a common ancestor. 2. Populations change over time through two mechanisms: natural selection and genetic drift -Natural selection states that those organisms with characteristics that help it to survive will be more likely to reproduce and pass on those "favorable" characteristics to their offspring. -Genetic drift is the random change in the genetic composition of a population due to chance events causing unequal participation of individuals in producing succeeding generations. 3. Eventually these changes will cause new species to develop, and is the reason for the diversification of today's organisms.
Natural selection is based on what 5 observations?
The theory of natural selection is based on the following assumptions about the nature of living things: 1. All organisms produce more offspring than can survive. 2. No two organisms are exactly alike. 3. Among organisms, there is a constant struggle for survival. 4. Individuals that possess favorable characteristics for their environment have a higher rate of survival and produce more offspring. 5. Favorable characteristics become more common in the species, and unfavorable characteristics are lost.

Why could natural selection not occur without genetic variation in a species?
Natural selection is a change in allele frequencies of a species which allows that species to better survive in it's environment. Without genetic variation there would be no change in the allele frequency of a species. However, with genetic variation there is a chance that one particular member of a species will be born with a random mutation which allows it to better survive in it's environment, thus increasing the chance that it will reproduce and pass on that genetic trait to it's offspring who in turn will pass it onto their offspring and so on. Without genetic variation all members of the species and their offspring would be exact duplicates of each other and no particular member would have an advantage over another.

Sexual reproduction means there is much greater scope for genetic variation of offspring. Variation is good for any species as it is this variation that allows for adaption e.g. the variation might provide some individuals with resistance to a new disease that affects the species, hence those individuals survive and thrive.
