We do it with domestic animals all the time.
naturally occurring selective pressures favor new traits, humans create new environmental conditions
There is some controversy on this; some scientist believe that Neanderthals were a sub-species of humans, and some believe that they were a separate species and not humans at all.
humans :)
When a group of organisms can interbreed they are considered a species. Humans can interbreed and produce other humans because they are the same species.
The scientific name for present day humans is 'Homo-Sapiens'.That is our species name.
Yes, it is, but don't ask me how!
For the same reasons technology has always been important to humans since our species first appeared about 200000 years ago in Africa. Humans create technology to help with their daily needs and the technology then makes human life easier (and in some cases possible where it previously was not possible).
It is not possible for humans to get vine's disease. This type of disease is only seen amongst grape vines and can be remedied through the use of pesticides if desired.
Theoretically it is possible, but "theoretical" and "probable" are two very, very different things.
Assuming they were possible, crocodiles mixed with humans or sharks mixed with eagles.
It is when a species is introduced into a new area. It could be caused by humans moving species or migration.
No, volcanoes did not create humans.
Rhino's are about to become extinct as humans kill them and create medicine from their horns!
The species name for humans is sapiens. Our genus-species name is Homo sapiens.
Since man has begun migrating they have dispersed species. whether they brought livestock, common or exotic pets, different plants. Humans play a huge role in species dispersal. Many species would not have migrated on their own but did only because people picked them up and moved them. When a plant is brought to a region and its spores are released they will create a new population in a new place.
Humans are a species of mammal.
As part of the environment of other organisms humans can have great effects on speciation. Especially adaptive radiation. As we contribute heavily to the extinction of some species other species flow into those open niches and radiate outwards to possible speciation.
