Aliens .... They come in UFO's and arise new polyploid species.
HYBRIDIZATION
polyploid
Polyploid
Organisms that have more than two complete sets of chromosomes are said to be polyploid. This often occurs in plants.
They both are mechanisms by which new species arise grad point
polyploid
Because new species have to adapt to their newly acquired surroundings.
Polyploid may instantly produce new species of plantsthat are often strongerthan rhier diploidrelatives
Evolution
Polyploid may instantly produce new species of plantsthat are often strongerthan rhier diploidrelatives
Through natural selection and evolution
If one animal has a mutation and breeds with another animal then a new species may arise. The gene of the mutation may be carried down in the babies.
