The first human like being is
The question asks for the *first* human-like being. To answer this, we need to consider what characteristics define "human-like" and how different hominin species evolved.
Understanding Hominin Evolution:
Hominins are members of the tribe Hominini, which includes modern humans and all of our extinct ancestors after the split from the chimpanzee lineage. Key features that evolved over time and make a species more "human-like" include:
Analyzing the Options:
Why Homo habilis is the best answer:
While earlier hominins like *Australopithecus* were bipedal, *Homo habilis* is generally considered the first to combine bipedalism with evidence of tool use and a somewhat larger brain. This combination of characteristics places them as the earliest recognized species within the *Homo* genus, and arguably the *first* exhibiting a suite of characteristics we associate with "human-like" behavior, even if those traits were still relatively primitive compared to later species like *Homo erectus* or *Homo sapiens*.
Therefore, the best answer is: Homo habilis
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.
The given graph shows the range of variation among population members, for a trait determined by multiple genes. If this population is subjected to disruptive selection for several generations, which of the following distributions is most likely to result?
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
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.
