They both proposed the theory that all matter consists of atoms.
Dalton proposed it in Dalton's atomic theory (i think)
Democritus was an ancient Greek philosopher who was a pupil of Leucippus. Democritus suggested that different types of small discrete particles formed all matter. He suggested that the properties of the tiny particles are what determined the property of the matter.
1)One problem with his atomic theory was that it claimed that all matter is composed of tiny indivisible atoms. We now know that atoms are divisible and are composed of smaller, subatomic particles (electrons, protons, and neutrons). 2)He also stated that atoms of an element are identical in mass- this is incorrect because all elements have isotopes (atoms with this same proton number but different numbers of neutrons) which means that atoms of an element do not have to have the same mass.

It disproved Aristotle's four-element theory of matter.

The ATOMIC THEORY states that all matter is composed of very small particles called atoms, and that those atoms cannot be broken apart.
It was either Terrence Ahlin or Einstein. I think.
The Big Bang Theory!

Darwin proposed the theory of evolution.evolutionvariationartificial selection
its not really a matter of who "discovered" the instinct theory but who PROPOSED the instinct theory is what i think your question is asking in which case i believe the answer--if my memory serves me right-- is William McDougall
