Evolution involves constant random experimentation, leading to many different kinds of results. Every ecological niche has more than one species, and more than one adaptation. Think of how many different kinds of creatures have adapted to living underwater, and the tremendous number of different adaptations for doing so. There is no reason why there would be only one adaptation for desert plants.
Cacti are primarily plants found in the Americas. Some have been taken to other areas of the world and introduced where they quickly become noxious invasive plants. Various prickly pear species are the prime culprits.
Becuse these plants have been taken out of their natural habitat. Dandelions have evolved to adapt to the conditions in the fields: the plants are adapted to different areas light conditions water conditions, the strenght of the wind etc. I hopw this was helpful!
During the Devonian Period is when vascular plants most likely evolved. The evidence of this time scale is that fossils dating back to the Devonian Period have been found.
Approximately millions because there are no forests in deserts.
An Adaptation. Adaptations are used to survive.
Pine trees.
Cacti are strictly plants of the Americas. However, cacti, especially prickly pears, have been introduced into a number of deserts around the world and they have become a noxious invasive species.Cacti are strictly plants of the Americas.

Charles Darwin's greatest scientific contribution is his work on the Theory of Evolution. Without it, the fact that plants and animals evolved from its ancestors would not have been discovered.

Depends on the type and location of the desert. Most deserts have endemic apex species. Most north American deserts have some form of cactus as the predominant specie, where as African deserts do not have endemic cactus species.It is safe to say that the prevalent plant species in a hot, dry desert is zerophytic.Of course not all deserts are hot, there are also cold deserts such as Antartica, where there are no plant species.Depends which desert.most are dominated by many kinds of plants which have been specially adapted to survive there such as cacti
Virtually all animals have "evolved".

The origin of plants goes back at least 510 million years ago. They evolved from chlorophyte algae and have been growing ever since. Plant life and growth is abundant in many places on Earth.

nope.well not that have been found.
Elephants have evolved with tusks! They have been hunted by poachers for their tusks, so they have evolved to not have tusks. :)
Any plant will prevent soil erosion. It's in their nature. Plants known as "pioneer species" are perhaps best suited for erosion control as these plants have evolved to thrive in areas that have been disturbed by landslides or construction.
