Reproduction
Populations evolve.
It is not correct to say that individuals evolved because it is not possible for an individual to change drastically over their own timelife. Species have the faculty to evolve as a whole not as individual organisms.
because the gravity of the earth is forcing you to love me than your parents.
Single individuals are naturally selected, but populations ( can be whole species ) evolve. Any mutation happening in the germ line of an individual will die with him. Only his progeny can inherit said mutation and evolve. Evolution is the change in allele frequency over time in a population of organisms.
An individual organism is one single organism of a species.
Species (under the Biological Species Concept).
Reproduction
No. Evolution is not valid. Evolution suggests that one species changes into another species. Given all that we know about DNA, there is no possible way for any one species to change into another species even with mutations. Mutations make the individual organism weaker than the average organism of the species population and in many cases causes that organism to be sterile. Even if the individual organism does reproduce, the weak trait will be covered by the dominant allele thus rendering the mutation dormant. There would need to be a simultaneous catastrophic production of the mutation on a mass scale within the population for the mutation to even show up on a large scale in the population. Even if this magically occurred, there would not be a new species, only a new trait that shows up in the species. There is not a single documented case of any species changing into a new species.
An individual organism is one single organism of a species.
extinct species
Genus and species are specific to each individual organism, so there is no genus species for all plants.
binomial system
Populations evolve.
POPULATION:)
its a population
In Sympathetic Speciation, a species evolves into a new species without any barriers that separate the populations.In Allopatric Speciation, a population divided by a barrier, each population evolves separately, and eventually two populations cannot successfully interbreed.
