Simply mutation and natural selection against the backdrop of the immediate environment.
Evolution is a slow, slow process which enacts itself over many generations. Species evolve to adapt to environments and to survive, which makes evolution the mechanism through which "survival of the fittest" succeeds as a natural order.
Homo-Sapien, there isn't a modern form of our species.
The new tools given them by molecular genetics have been more helpful than fossils and modern morphological consideration to track the evolutionary procession of species.

Modern scientists now use genetics to help explain the theory of natural selections.
The ability to read, modify, and transform DNA is what past scientists did not have. Genetic engineering is another factor that Darwin could not explain. These are all modern scientific breakthroughs with that help of modern technology that Darwin lacked.

Yes. Plate tectonics is part of the current principal theory that seems to explain the formation of geologic faults, rifts, earthquakes, sea floor spreading, and even some diversification of species, among other phenomena.
Scientists say that hominids diverged into two different creatures over time: Apes and humans
There is no exact way to tell. But scientists can make a good guess. Calculating the overall size and muscle mass of the species will give them an approximate idea on how the skin would stretch over their bodies. As for color, there is only basing the ancestral color off of a more modern version of the species.

Homo habilis means "handy man" in Latin, reflecting the species' ability to use tools. Scientists consider Homo habilis as one of the earliest members of the Homo genus, distinguished by their primitive stone tool-making abilities.
Comparative anatomy of certain species of dinosaurs, early birds, and modern birds show they are related.
Homo-Sapien, there isn't a modern form of our species.
how do modern scientists describe the makeup of matter
Megaladon or Carcharodon megaladon is an extinct species of shark identified though fossil teeth and vertebrae that lived 25 to 1.5 million years ago. Estimates suggest it was a 67 ft shark similar in appearance to the 20 ft modern day Great White or Carcharodon carcharias. There are no megaldon's alive today.
