Nope. All living creatures are constantly evolving. Natural selection is continuously working at flushing out the unfavorable genes, placing forth the genes that better-equip an organism to survive with every succeeding generation. A major reason for why some people deny evolution is because of the sheer length of time required. Humans have a rather limited sense on time. We can grasp years, decades and centuries well...millennia, not so much. When you hear the words "100 million years," however, all intuition goes out the window. This is where such ignorant rebuttals like "If evolution is true, why isn't it happening now?" come from -- the inability to comprehend time at that magnitude.
That's exactly why evolution is false if it were true we would see evolution now as animals evolving from water to air from air to water there's no such thing happening no such thing in the fossil evidence nothing new under the Sun read the Bible it will scare the hell out of you

No- everything is in a constant state of evolution. Humans are still evolving, we can see bacteria and viruses evolve from day to day. People who try to deny evolution by asking "why don't we see organisms evolve now" are ignorant of biology- we do see this. Even in animals with long generation times, even in humans with our ability to belie some of natural selection through technology and medicine. For example, our average height as a race has changed greatly in just the last three hundred years- yet our average cranial size has DECREASED.
evolution takes millions of years its caused by dominate mutations, put your hands in a bowl of water for 10 minutes, your hands will wrinkle this is because of evolution its your hands adapting to the water to better grip objects and it does by an average 14%.
Creatures continue to evolve, from generation to generation. It is a fact that humans for example, have become taller on average than our ancestors only 100 years ago. People of African descent in America have become less darkly pigmented than their forebears over a period of centuries. This is consistent with evolutionary theory. It is principally the evangelical devout, who themselves can't evolve past Bronze Age hearsay that deny the concept, though the evidence for it is immense.
Evolution is the process by which something simple becomes something complex. Not all creatures go through evolution; only the ones through natural selection. So a creature is either going to stop evolving when it becomes extinct, or it will stop evolving whenever what is causing it to evolve ceases.
For example, what causes us to evolve as human beings is genetics. Our genetics are widely varied because of evolution. So, in order for us to stop evolving, we have to stop mating with those who have different genetics, or mate with those who have similar genetics. Eventually, we do die out because of that so...

Human evolution is as simple as this... If you see an attractive and healthy looking man with a great personality, do you go for him? Or do you go for the unhealthy man with a bad personality?
Natural selection. Yes, we are still evolving, and we will continue to evolve as long as our species exists. Everything is constantly evolving to adapt better to its environment and produce the healthiest offspring.
Everything changes over time. Rivers change their course, mountains melt into seas, the crust of the earth moves and the seasons change. Time changes everything, including living beings; this is built into our DNA, as we continuously exchange DNA with our mates to produce offspring. There are random mutations that happen in alleles, at a known periodic rate, which allows for variation at the DNA level. Additionally, there is essential plasticity in DNA; look at the variety of dog breeds, and you will see such. Selection and survival are other mechanisms to cause variability. But one species observed giving birth to another is indeed rare, and there are few (if any) examples. This has led to doubt over the standard model by some. But rarity does not prove inability.
