The nineteenth century saw significant advancements in microscopy, including the development of the compound microscope, which used multiple lenses to magnify specimens. These improvements allowed scientists to observe finer details and led to the formulation of new theories and discoveries. Furthermore, the invention of oil immersion objective lenses and improved lighting methods, such as the introduction of electric light sources, further enhanced the resolving power and clarity of microscope images.

The evidence is by chemical analysis.
The development of the microscope led scientists to the discovery of new living things called microscope organism. These newly discovered organisms were to small to be seen with the unaided eye.
I don't know about Wallace, but Darwin spent a lot of his time in the Galapagos Islands where he saw what he thought was natural selection in action without interference from, or as a response to, outside sources like mankind.
It really depends on a microscope when you look through it! If you put the led of the 4x mirror then you would be able to see the cell 4 times bigger however if you put the led of 50x mirror then obviously you would be able to see the cell 50x larger! Normally the 4x-50x mirror microscopes are the school ones furthermore if you bought a expensive scientific microscope you would be able to see the cell atleast over 1,000x larger!!!

The telescope and its various improvements
farming improvements led to availability of more food which led to population explosion.
The evidence is by chemical analysis.
Farming improvements in the Middle Ages led to greater agricultural yields, which attributed to a dramatic increase in population. The revival of trade led to a growth of cities.
trade and transportation and the things they had around them
In 1936, improvements in the design and construction of the wash tie led to its gaining widespread acceptance.
This unit features and requires LED as a light source.
I'm led to believe by your grammar that you have never laid eyes on either one, so in what way should it effect you?
The vacuum pump was the critical precursor to the invention of the hot-filament light bulb. Indeed, improvements in vacuum pumps have continuously resulted in improvements in incandescent light bulbs. And of course, such things as metal working, glass working etc.
It was the beginning of the end for Imperialism, which may be regarded as good by some. It also led to improvements in aviation, communication, etc.
