Evolutionary Science is not disputed. The fact that rhetoric spouting fundamentalists try to cloud the facts speaks more to the desperation of those fundamentalists than against Evolution.
Evolution is an evolving field, as are all sciences. Anthropology is one of many fields which are used to examine aspects of Evolution.

All theories are under challenge. That's why they're still considered theories, and not laws. It's not that they're unfounded, just not totally proven. You know, that old "exceptions to the rule" thing?
Most anthropologists take evolution as fact. Way too much basis for it. The questions arise from the different species evolving at different rates. Why? Why have sharks, turtles, armadillos gone around for millions of years virtually unchanged, while other species adapt every few years? Makes for interesting discussions, to be sure.
I am unaware of viable alternate theories, at least ones that don't involve evolution to a point.
Thanks for the good question

There will always be alternate theories, but as technology improves so does the chances of finding one correct explanation. Darwin may have not had all of the answers, but his original theory still holds true.

basically Darwin´s theory is true, with some new discovery's and investigation some things on this theory have been accurate or amplified, but the bottom line is true and verify.
anyway evolution theory does not have nothing to do with anthropology, it is a biological matter.

The current theory of evolution, does not hold water. Mutations rarely have positive effects. How could the dinosaur to bird transition have survived? Changes occur minutely, evolution claims unbelievable jumps that include, types of skin, breathing apparatus, reproduction, any animal with that many different traits is a different animal, period.
There is a difference between operational science and theoretical science, theoretical cannot be repeated or manipulated. Most dating methods are theoretical and not operational in process, so any evidence suggested there is suspect.. There is actually more evidence that suggest the creationist may be closer to correct.

Rather than glean your information from "what one of your friends told you" and this informal and unedited site, I suggest you actually acquire or borrow a book about the subject and read it thoroughly.
Avoid all the media hype about this subject and read it with an open mind. There are many reputable books printed on the subject.

Darwin's theory of evolution has been challenged by religious groups ever since it was first published. These challenges continue despite a growing body of evidence that supports evolution.
"Creationists" take a literal view of the Bible and believe that God created the first humans, making Adam more or less from scratch and using one of Adam's ribs as a starting point for Eve.
More recently, adherents of so-called "intelligent design" argue that a "higher being" had to direct the creation of people and other living things, because they're too complex to have evolved more or less by accident.
One of the problems is with the language involved. In common use, the word "theory," means speculation or conjecture. But in science, "theory" refers to a fact that has been verified by experiment or observation. For scientists, unproven ideas are called hypotheses. Therefore, people who attack the theory of evolution as "just a theory" show, among other things, their unfamiliarity with the context in which the word is used.
Apart from that, Darwin didn't suggest that humans and other organisms evolved by accident. As living things reproduce, genetic variations will make some individuals better able to cope with their environment, to find food, to compete with other species. These better-equipped individuals will be more likely to reproduce and pass those variations down to their offspring.
For example, say that a group of our distant pre-human ancestors (not monkeys, pre-humans) lived in a part of the world where vegetation was abundant. They ate berries and roots and nuts. For them to digest this food, it needed to be chewed thoroughly, ground up well before swallowing. Their most important teeth would have been their molars.
Over time -- tens of thousands of years -- the climate changed, and the berries, roots and nuts became less available. Some of these pre-humans, through genetic variations, had developed stronger front teeth, the incisors that are used for eating meat. Even though these individuals had not yet developed the intelligence to hunt other animals, there was plenty of meat available to scavenge. The individuals with the better-developed front teeth became more likely to survive and to pass this trait on to their offspring. After a time, that trait became common.
These changes show up in the fossil record, which has provided the basis of support for Darwin's theory.
It can be difficult for some people comprehend all of this because the time scale is so hard to imagine and the length of a human generation is so long. For example, there have been only about 100 generations of humans since the time of Christ. For more perspective, there have been only 12 or 13 generations of Americans since the Declaration of Independence was signed in 1776. Those aren't enough generations for genetic variation to lead to any significant changes in humans.
However, the principles of evolution have been shown in domesticated animals, insects, and other organisms. For example, dogs are descended from wolves, which still exist in pretty much the same size and shape as they did millennia ago.
Wolves that ventured close enough to ancient humans were able to get scraps of food. Wolves that showed less fear of human environments were better fed and passed on this lack of fear to their pups. Over time, dogs became part of the human group.
Humans noticed that some of these animals were good at doing certain things (of course, with little training). The ones that showed aptitude for important tasks, such as hearding sheep or helping in the hunt, were the ones that got more food from their human masters, and thus had better chances of survival.
That kind of evolution is easier to notice because within one generation of humans there can be 20 or more generations of dogs.

I believe that his theory of natural selection is pretty widely accepted, but I don't know exactly what he said about species evolving into other species. And evolution has, of course, been challenged.

Widely accepted but never really proven. Fact is that at one time the theory of the Earth being flat and the sun orbits the earth was also widely accepted by the scientific community.

Monkies evolved from ugly people.
Ugly people only sllep with other ugly people,
and they had ugly kids.
Before long their grandkids were SOOO ugly they were thrown
out of the village, and grew up in the woods with all the other uglies.
Inbreading caused people to be born with tails, and grow fur.
