The modifications of arthropod appendages has shaped the formation of different groups, such as centi/millipedes, crustaceans, arachnids and insects. The most primitive arthropods are centipedes and millipedes, using all their legs as walking legs. More advanced groups, differing from this ancestral state, modified their walking legs into mouthparts, antennae, pedipalps (arachnids) or flippers (crustaceans, look at a lobster tail).
Look carefully at an insect face and you'll see it's a fused mess of segments with the legs still attached! Stick insects and beetles are a good example, other groups have modified their palps (mouth-legs) into unrecognizable structures such as mosquito or butterfly probosci.

How many jointed legs do arthropods have?
The number of legs varies by species. Hexapoda like the insects have six; decapoda like lobsters and crabs have ten (including specialized appendages); myriapods like millipedes may have over 700.
What does Darwin theory of evolution explain?
The theory of evolution by natural selection. It explains evolution; the change in allele frequency over time in a population of organisms. Why organisms change over time in differing environments.

What is an example of micro evolution?
You are an example of human micro-evolution as the population of humans has changed allele frequency over time. Micro-evolution is just evolution; change over time.
