Australopithecus: They were hominids not human - like apes.
Early humans are known as hominids. Australopithecus was the first human-like creature, that lived in Africa about 5 million years ago. Their brains were 350 to 450 cubic centimeters, the size of a gorilla. Homo habilis, which was more human-like, lived two million years ago and was the first to use stone tools. Their brain volume was about 700 cm3. The Neanderthals, which are more modern humans, are classified in the same species (Homo sapiens) as today's humans. However, living humans belong to a different subspecies, Homo sapiens sapiens. Although the Neanderthal brain was larger than that of humans today, it does not mean that the Neanderthals were more intelligent, because brain size is related to body size and the temperature of the environment.
The volume of a human brain, otherwise known as cranial capacity, varies depending on several factors, such as age, environment, and body size. The volume is usually measured in cubic centimeters (cm3 or cc). Modern humans have cranial capacities from 950 cm3 to 1800 cm3, but the average volume of a modern human brain is 1300 cm3 to 1500 cm3.

Homo erectus had brains that ranged from 800-1200 ccs. 1200 ccs is in the low end of normal for a Homo sapiens.
It sounds like you're talking about australopithecines. If it MUST be a species of Homo, the only possibility is Homo habilis.

I would say that Homo Floresiensis, the recently discovered so called Hobbit in Indonesia is the only one to qualify since its brain is about 400 cc. I like to think that all members of the genus homo are apes including ourselves. It makes everything a little clearer when we don't arbitrarily separate ourselves from our ape relatives.

Ausralopithecines - first hominids- 500 cm(3)
Homo Habilis- 700 cm(3)
Homo Erectus- 1000 cm (3)
Neanderthal- 1450 cm (3)
Cro-Magnon -modern humans- 1400 cm (3)
you decide..... i say the first hominids. Ausralopithecines
