What are the different ways of …

Early man or primitive man obtained food by the following methods: 1) in the early stages of life the early man depend on the fruits and vegetables . 2) after a long time they start to kill animals for food firstly small animals but later they hunt big or wild animals and eat the meat of the animals for survive in nature. 3) in the early ages they travels here and there in search of food but many years later they start to grow crops this is the major development of the life of primitive man and live a stable life when they grow crops they don't want to go for hunt .

Early humans would have obtained food through a number of ways, such as gathering, hunting, scavenging and fishing. Gathering would involve collecting plant foods such as seeds, nuts, berries, fruits and tubers.
(i) That gathering was practised is generally assumed rather than conclusively established, as there is very little direct evidence for it. While we get a fair amount of fossil bones, fossilised plant remains are relatively rare.
The only other way of getting information about plant intake would be if plant remains were accidentally burnt. This process results in carbonisation. In this form, organic matter is preserved for a long span of time. However, so far archaeologists have not found much evidence of carbonised seeds for this very early period.
(ii) In recent years, the term hunting has been under discussion by scholars. Increasingly, it is being suggested that the early hominids scavenged or foraged* for meat and marrow from the carcasses of animals that had died naturally or had been killed by other predators.
It is equally possible that small mammals such as rodents, birds (and their eggs), reptiles and even insects (such as termites) were eaten by early hominids.
(iii) Hunting probable began later - about 500,000 years ago. The earliest clear evidence for the deliberate, planned hunting and butchery of large mammals comes from two sites : Boxgrove in southern England (500,000 years ago) and Schoningen in Germany (400,000 years ago)
(iv) Fishing was also important, as is evident from the discovery of fish bones at several places.
