Faith belief... based upon the belief that we share the same ancestor.
-_- not so much that as genetic evidence that shows humans have certain genetic differences related to intelligence not shared by any other living ape species.
If we split from the same common ancestor, they lived in exactly the same environment.
Humans have different common ancestors between ourselves and gorillas than between ourselves and chimpanzees, and there were a lot of transitional forms between that split and now. Yes, that last common ancestor lived in the same environment by virtue of being a common ancestor, but evolution didn't jump from that immediately to humans and gorillas. It is the non-shared ancestors that existed after the split that lived differently. Plus, I was describing why other apes such as modern chimps are not currently on an evolutionary path that will lead them to becoming more like humans in the future, I wasn't describing why all those evolutionary paths didn't end up with humans in modern day.
In fact, since they supposedly arose out of Africa, they lived alongside one another.
You do know that not all modern great apes are native to Africa, right? Orangutans live in Asian islands, for example.
Hmm, according to evolutionists we have several different species of finches occupying the same ecological niches.....
Citation, please. Also, same exact ecological niche in the same environment? Because organisms that don't live in the same exact area can share a niche. If they have overlapping but not identical territories, that is feasible.
Plus, while I did say two different species cannot share the same niche long term without competing for resources too much, I never said they couldn't short term.
Actually according to actual mutation experiments with plants and animals, the same stuff comes about over and over and over and over and over and........

1. This article is over a decade old and comes out of India, from a publisher not considered to be particularly reliable. I would suggest Nature articles, or perhaps Scientific American.
2. Dr. Wolf-Ekkehard Lönnig, whom is the sole author of this article (generally, not a good sign with works in biology, especially considering how much work would have to go into the study described. Either other people weren't accredited that should have been, or they refused to have their names on this), is a well known creationist backed by the Discovery Institute and Evolution News (which is also a creationist site).
3. The article mentions purely homozygous lineages of plants being experimented upon. However, his entire article depicts not one instance of him breeding plants himself. He doesn't perform a single experiment for his paper, instead trying to utilizing variations in barley cultivars. Despite bringing up mutagenic agents in the first paragraph, he uses none. Plus, the genome of barley wasn't fully sequenced until 2012; 7 years after this crap was published. So he has no basis for the normal genes to compare mutations with, even if he bothered to perform an actual experiment. Which he didn't.
4. Nearly half of the references for this article are papers that Dr. Wolf-Ekkehard Lönnig himself participated in. That's quite the faux pas for a paper trying to give the illusion of being scientific.
5. There are no non-creationists that claim the law of recurrent variation is a thing.
6. All he observed was that thanks to ARTIFICIAL SELECTION BY HUMANS, certain traits kept popping up in barley cultivars. You know where humans put barley plants that don't have traits we personally find desirable? In the mulch pile. The traits are repetitive because there are specific traits humans select for in barley plants consistently, and also because people that breed barley cross lineages all the freaking time. These aren't homozygous lineages at all. Remember, most traits don't follow Mendelian genetic patterns. It is not uncommon for plants to even express entirely different traits just in response to hormonal changes.
7. Even if this guy actually had bred plants himself and utilized mutagenic substances as was stated early in the article, mutagenic substances don't produce random mutations. Most of them make A and T substitutions more likely. As a result, it is impossible to instigate all possible likely mutations artificially through use of mutagenic substances.
Seriously Justa, did you even read past the first paragraph or two of this crap? Red flags all over the place.
But hey, why worry about what actual experiments in animal and plant husbandry showed when we can just claim anything we want, right? In fact, its that recurrent variation that caused them to all but abandon mutation as a way to bring about new forms in plant and animal husbandry.....
-_- since mutations are pretty random, waiting on a trait to appear can take ages, especially if the organisms in question take years for each new generation. As a result, it is easier to just cross two individuals that already have different desirable traits to get offspring with both rather than wait for one lineage with one desirable trait to eventually experience a mutation that grants them the second desirable trait.
-_- the reason for that is because mutations AREN'T recurrent. If they were, it would make waiting for the desired mutation more viable because it'd be much more likely to occur if it already did in a different lineage of the same species.
Of course, since different mutations can end up producing practically identical effects, it is possible for a trait to arise independently multiple times, but it won't be the same on a genetic level unless humans intervene to make that outcome more likely. Even then, that's pretty difficult to achieve, and it absolutely requires restrictions on the gene pool of the population being worked with.
