The first human like being is
The first human-like being is believed to be Homo habilis.
Homo habilis, meaning "handy man," is an extinct species of the genus Homo that lived approximately 2.4 to 1.4 million years ago. They are considered one of the earliest members of the human genus and are known for their tool-making abilities, which set them apart from earlier hominin species. Homo habilis is considered a transitional species between our more ape-like ancestors and later human species, such as Homo erectus and Homo sapiens.

Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
