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.
Both. People have adapted to their environments through cultural practices, such as building shelters or creating clothing to survive in different climates. Similarly, humans have evolved over time through genetic changes that have been passed down through generations, allowing for better adaptation to various challenges.
Vascular plants most likely evolved around 400-450 million years ago during the Ordovician period. Fossil evidence, including early vascular plant fossils such as Cooksonia, suggests that these plants emerged during this period. Additionally, molecular clock studies also support this time frame for the evolution of vascular plants.
There were simple plants in the Cambrian Period(542 - 488.3Ma). Fossil algae has been found in Cambrian Rocks. Evidence of primitive algae from the Precambrian Super-Eon has also been found but exact classification has not been established. It is true that embryophytes (Plants we most recognise) did not evolve until the Ordovician Period(488.3 - 443.7Ma).
Approximately millions because there are no forests in deserts.
Pine trees.
A trait is a characteristic or feature of an organism, while an adaptation is a trait that has evolved to enhance an organism's survival and reproduction in its environment. Adaptations are traits that have been shaped by natural selection to better suit an organism's ecological niche.
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".
nope.well not that have been found.
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.
Elephants have evolved with tusks! They have been hunted by poachers for their tusks, so they have evolved to not have tusks. :)

Yes. By electrically reconnecting plants (in insulated containers) back to the Earth, you bring them into equipotential with the ground state of the Earth. This is the condition that plants have naturally evolved in. The benefits of this reconnection have been rediscovered and are being presented by a company called Earth & Grow.
There are cold deserts and there are cold winter deserts as well as cool coastal deserts. The coldest and largest desert is Antarctica. Temperatures have been measured there at less than -130 degrees F.
