Humans (Homo sapiens) have 46 chromosomes which make up their nuclear DNA genome; this number is known as the diploid number. Half of these 46 chromosomes are always donated by the mother and half by the father. So, mom and dad each contribute 23 chromosomes—the haploid number—to their offspring. Therefore, the 46 nuclear chromosomes, that all humans possess within their cells, are actually 23 pairs of identical chromosomes. (To be more precise, females have 23 identical pairs, while males have 22 pairs that are identical and the sex chromosomes, X and Y, are paired but not identical.) This diploid number of 46 (23 pairs) is, however, unique to humans among their alleged primate relatives. Genetically speaking, those species which have DNA sequences most similar to that of humans are the great apes. Each of the four species of ape (chimpanzee, gorilla, bonobo, and orangutan) possesses 48 chromosomes or 24 pairs, compared to the 46 chromosomes of humans. However, the genetic difference between Homo sapiens and their alleged primate relatives is significant. Of the four species of great apes, also known as hominids, the chimpanzee (Pan troglodytes) harbors the most similar DNA sequence to humans, making it genetically the closest to Homo sapiens.

Interesting, if you think that the evolution is made by aliens, what will be the next evolution they will produce is the question.
According to Simon Conway Morris, a professor of evolutionary palaeobiology at Cambridge University, anyone planning for alien contact should prepare for the worst. Evolution on alien worlds, he said, is likely to be Darwinian in nature. Morris argues that life anywhere else in the universe will therefore probably have important similarities with life on Earth – especially if it comes from Earth-like worlds that have similar biological molecules to ours. That means ET might resemble us, warts and all, with our tendencies towards violence and exploitation.
