What do you call observing single nucleotide polymorphisms accumulating in microbial populations over time? Scientists in the agricultural and medical fields have collected biological samples over the last 100 years and stored them so that they can be revived and have their DNA sequences typed today. I personally have physically seen the accumulation of DNA changes over time that confer things like drug and pesticide resistance through well characterised biochemical pathways. Eventually these specimens will evolve into different species as those that have been exposed to the agents mutate in one direction and those that have not will stay more constant.
Due to the very nature of evolution that it occurs over millions of years, we can't watch new limbs or organs develop in their entirity in multicellular organisms, but we can (and do) observe the basic subunits evolving.
Species have been observed to genetically change in response to their environment. Fact. Geographically distinct populations of the same species change in different ways and become distinct from each other in terms of the biological species concept. Fact.
