There are more than 0 humans, so yes we produce more offspring than needed to survive, however humans aren't often hunted or killed by other species so it would be difficult not do. Usually animals have many more offspring than humans do, but they are also part of the natural food chain, so that is needed to survive.
As you said- different species. Diferent species have different geneticmaterials, and it does not match up. Like trying to put a DVD in a VCR.
Elephants and humans produce low numbers of offspring. Organisms that produce low numbers of offspring produce offspring that are most dependent on the mothers.
This might be thought of as a species if the group indicated was large enough to include all of the potential members that can breed and produce viable fertile offspring. This would mean that animals which can breed and produce infertile offspring such as horses and donkeys which can mate and produce offspring are not of the same species. This situation would be within the bounds of the question. When a group which is of one species but is of limited such a limited population that the only can breed with a small number of individuals and produce a fertile offspring it would be described as a bottlenecked population. This can lead to severe genetic drift in that population.
Neanderthals and humans are genetically similar. Less than one percent difference in their DNA.
Animals don't always produce identical offspring. Like cats for an example.
The only species that has to rely on currency to survive - is humans !
Animals or even humans couldnt produce offspring.
Mammals produce a low number of offspring. Take humans, cats or dogs for example xHope i helped ;P
Humans produce few offspring slowly
It is the length of time to produce offspring. In humans, it is about 9 months.
Artificial Selection
