Introduction
Evolution is a key unifying principle in biology. As Theodosius Dobzhansky once said, “Nothing in biology makes sense except in the light .
Evolution happens on large and small scales
Before we look at the evidence, let's make sure we are on the same page about what evolution is. Broadly speaking, evolution is a change in the genetic makeup (and often, the heritable features) of a population over time. Biologists sometimes define two types of evolution based on scale:
Macroevolution, which refers to large-scale changes that occur over extended time periods, such as the formation of new species and groups.
Microevolution, which refers to small-scale changes that affect just one or a few genes and happen in populations over shorter timescales.
Microevolution and macroevolution aren’t really two different processes. They’re the same process – evolution – occurring on different timescales. Microevolutionary processes occurring over thousands or millions of years can add up to large-scale changes that define new species or groups.
First, we'll look at several types of evidence (including physical and molecular features, geographical information, and fossils) that provide evidence for, and can allow us to reconstruct, macroevolutionary events.we'll finish by seeing how microevolution can be directly observed, as in the emergence of pesticide-resistant insects.

Evolution is a theory wherepeople think that we came from humans and ove the years that these animals like apes or any monkey basically just frormed to humans year by year. The evidence for it is none. All the supposed evidence is beased o human thinking. Hear this a Scientist says that species have similar bones to our but not the absolute completely same bones. And how about now why havnt these apes or mokey turned into humans? Yet how did apes come to the earth how were these apes created or formed whatever they call it? Most likely like a planes needs a creator so do we humans we cant come out so perfect and hen i say perfect cause obviously no one is perfect but like how did the earth become so suitable for living it wasnt the big bang.
