Man is definitely not the most recently evolved
species on earth. Corn, for example, didn't exist
before man, it was produced by humans. There
is some evidence for origin of new species of
insects in just a few thousand years. Many of the
native organisms on the Big Island of Hawaii are
younger than humans, as the island is only about
a million years old. Humans are not the "most
evolved" species. All living organisms have had
the same length of time to evolve, though, of course the species have not all originated in
their present form at the same time. Humans are
actually relatively primitive mammals in some
respects, retention of five digits on hand and feet,
for example, and absence of specializations such
as horns, fangs, claws rodent-like incisors, etc.

The HIV virus must, per definition, be a newer species than humans, since the H in HIV is for "Human" so we wouldn't use that species name for a virus that used a non-human host. More generally, parasites evolve fast. Bedbugs and lice are probably also newer species than humans.
But species evolve all the time, they don't suddenly "come up". The fact that we don't talk about "homo sapiens" when referring to fossils older than some 200,000 years, while most other modern species have existed for millions of years, is above all because we are Home Sapiens ourselves and therefore find the small differences between, say, a modern human and a Homo Erectus more important than the difference between, say, a modern icebear and a 200,000 years old icebear.

theoreticly all life evolve from a single type of creature,, one celled or not,, so we all started out at the same time. the short answer to your question is that no one knows. to know scientists would have to make a genetic tree of every species on the planet,, birds, bugs, mamals and then compare them. theer are milloinos of species if you include bugs. If your question was more general as to when humans as we are now evolved it is estimated to be about 60,000 years ago, but just because we evolved didn't mean everything else stoped,, everythinl else was also evolving at the same time, but we have no way of knowing. Is it possible for some other creature to evlove our inteliigence or even greater or different?,, possible,,but it has to do with enviromental pressures,, and remember that we all strarted from the same creature,, so any intellegence evolved would most likely be like ours.

Evolution is an ongoing event, with species developing and dying out all the time. The question is whether we should be preventing some species from dying off, like the Koala Bear. The environment that sustain them began changing long before the encroachment of man. Clearly, they were not meant to survive.

Evolution goes on constantly. Plants and animals continue to evolve all the time. We like to think of ourselves as the "peak" but this is not accurate because evolution is not goal-directed. Organisms change constantly in response to a changing environment.
We may have taken the evolution of human beings into our own hands as a result of advances in medical science. Individuals who might have died before they reached the age to reproduce, now live longer because we have cures for diseases that would have elinimated them from the population. That's just my observation, but it seems to make sense.

Man is the most evolved creature.It evolved from cromagnon, some 100000 years ago.Judging from the anatomical and other features, there is no other species comparable to man.Evolution is going on continuously in all forms. With cladogenesis new species arise from the old one.Whether man would split to give rise to other species lies in the womb of future.

No evolution on this planet..
Man and Woman are the first and the latest creatures..
And any other living creature will not come after them..
