hybrid of different species (tiger to lions, lions to puma, dogs to cayote, wolf, dolphins to whales etc) when induced by humans it cause severe biodiversity loss. however i want to know why there are people who actually do it, are you one of them? tell me why?

A lot of times hybridization happens in zoos (ex. liger). Hybridization of plants is extremely important for farmers growing crops such as corn. As far of animal hybridization goes, the only reason scientists would do this is for research in genetics.

There used to be more than one species of humans but they died out. Technically there are animals that are our species like chimps, but are not humans. Some researches even believe we should be part of the same genus as well. All dogs are one species just different breeds like we have different races.  There are probably so many species of frogs because they can all cohabitate on the earth without interfering with each other and killing each other off.

A "dot" and a "rag". \nNo, seriously, in most cases animals need to be of the same species (not "family" as a previous answer stated) to be able to produce offspring. However some species of the same genus can mate with each other and produce offspring, such as horses and donkeys, lions and tigers, some smaller cat species, dogs and wolves etc. Mostly the interspecies breed is infertile. This possibility is probably not as unnatural as one think but might rather point out that our (scientists') definition of a species as the basic classification unit of life, still contains elements of artificiality.\nYour mentioned species are not known to interbreed, though.

See, this is why I go by nature and not a book.  Nature is so wonderfully diverse. I just can't imagine the One who gave us thousands of insect varieties, not to mention the platypus, wanting us all to believe the same thing, have sex the same way, wear the same clothes, etc.

Biodiversity by definition means a variety of life: the different plants, animals and micro-organisms, their genes and the ecosystems of which they are a part.\n\nBiodiversity should be conserved because each species plays a role in its ecosystem. As species become extinct, the equilibrium or balance within the ecosystem is altered. Eventually, these alterations could have a negative impact on human life on this planet. \n\nSee chapter 11 of this online textbook for values of biodiversity: http://www.dbc.uci.edu/~sustain/bio65/Titlpage.htm

by saying they are "like another species" is saying they are not human. I would say that is racist or be careful how you ask your questions if that is not what you mean.

Good thing, yes.  But on the endangered species list.  There are lots of fundamentalists who would seek to tie the two pretty closely together.

It's good that they're finally coming out into the open about human-cow hybrids, but they've been doing that for years. Look at Margaret Thatcher for example.\n\nBut seriously, an embryo is not a human or a cow, and I doubt they would allow this to grow past a small number of cells. They are created in fertility clinics and discarded all the time. I don't have a problem with this.

Of course. It lead to genetic isolation, then evolution which gave us new species. Look at the ratities as an example.

It's the most likely skeptic's explanation. However, parthenogenesis does happen sporadically in higher animals, and rarity of such an event would satisfy both the scientists and the believers (who would claim it as a miracle).

Ahh, another Nature vs Nurture discussion.  Of course it is both.  If we didn't have the genetic component, our early anscestors would have eaten non-healthy food and the human race would have died out.  For the environmental aspect, we learn to like what is around us and is easy to get.  If pig farmers couldn't get used to the stench, then no one would be pig farmers.

Extinct species, if not extinct by human activity (shooting them, cutting their forests down, etc.), have extinct for a reason - they did not fit well to the enviournment.\nRecreation of such species may destabilize the delicate balance of nature.\nMoreover, any human interferance with nature, whether trying to do good or bad, can only harm it.\n\nThere are two (1.5) reasons. I think you can start with these, and probably the rest will come to mind after writing this. If not, I believe that other people will have further ideas.\n\nGood luck!

It would certainly matter if it were a different animal- I could do that without it significantly hurting my career, but I would lose a lot of time doing the things I love- the bald eagle would be a tough call, since it's so emotionally evocative.  To save gorillas, certainly- Algae, without a second thought-spotted owl, no way.  For me it would depend on the importance of the animal to the overall ecosystem, to the survival of humans as a species, and my own emotional response to the animal.  I doubt losing the bald eagle would have a terribly significant effect on the ecosystem compared to, for example, the rabbit.  Losing gorillas would likely have almost no effect on the ecosystem in general, but they are so much like us, and have such a close link and intelligence, that I would hate to lose them.  The trauma done to the ecosystem with a loss of algae would be unimaginable-Human probably wouldn't survive it.  Spotted owl?  There are very few of them, the niche is already taken by others which would move in to replace them, they have no discernible effect on human life, and I have no emotional attachment to them.  This may all seem cold, but it's how humans are-It's why we use pictures of cute baby seals, instead of salamanders, to elicit donations.

Currently I would put the probability at very low, but not impossible. True there are vast wilderness for animals to Hide in, and we are finding large numbers of new species all of the time. We, however, are not finding very many new species of large land animals. Also, the US Northwest, even though definitely a wilderness is not all that unexplored. It is much more likely to find a new large animal specie in the Amazon than The US Northwest.

Actually, ALL species of the animal kingdom engage in homosexual behavior...so yeah it IS nature intended. Christians have a problem with anything they can't control. They're also brainwashed and can't think for themselves.

Ligers and Tigons are sterile from birth, so there would be no offspring.  However, if one were to unlock the secrets behind genetic recombination, you could sample DNA from both animals and possbly splice a new, third hybrid ... perhaps a Tigron.  Sadly, natural pathways for an enhanced hybrid from these two creatures is impossible.

Some times people kill them for the "sport" and even more for the MONEY!  Yes, like the tusks of elephants for the ivory.  It is really sad but it is true.  Minks get killed for their fur....but that has slowed down but it still is happening.  I think more people are aware of the crualty to all animals espically endangered and many have woken up to the wrong doings.  However, there are still some boneheads that don't quite get it.(But that is true in life)  PITA ia a great program trying to protect animals.
