when did humanlike life appear on earth?

Answer 1

Well, the first ever living things on earth kinda looked like sperm.

Answer 2

Human-like life first appeared on Earth near Helena, Montana on a Tuesday, around 11:30am in the year 1658. A little-known fact, but true. The first human-like being was named Ambrose, and operated a hardware store, specialing in evolutionary ladders. The higher one climbed, the more human-like one became. But, Ambrose, not being the most intelligent of pre-people, forgot to warn customers not to step above the next to last step on the ladder. Well, of course, being curious critters, they did. And, passing right beyond becoming human, they fell off the top of the ladder, sustaining genetically transmissable brain damage, and became politicians. The planet hasn't been the same since!

Answer 3

Primates evolved from shrew-like animals about 50 million years ago. Primitive apes began to evolve from monkeys 22 million years ago. When Europe warmed up 10-14 million years ago, a great ape migrated there and diversified into many species, one of which was ancestral to orangs another was ancestral to gorillas and a third ancestral to chimps/bonobos/humans. When Europe cooled 10 million years ago the apes migrated south to Africa (ancestors of humans/chimps/bonobos and gorillas) and Asia (orang ancestors). We have fossil evidence that human ancestors (Australopithecines) split from chimp/bonobo ancestors 4.5 million years ago. But evidence from molecular genetics suggest a more complicated story, where ancestors of humans and chimps began to split about 10 million years ago, but occasionally passed genetic material (interbred) until 4-5 million years ago. The 4 million year old ancestors of humans, Australopithecines, looked more chimp like than modern human like. It was not until Homo erectus evolved from Australopithecines over 1 million years ago do we have something starting to look like modern humans. Homo sapiens first appeared from related hominid species 120,000 years ago.

Answer 4

Here, meet our relatives:

Sahelanthropus tchadensis. 6 to 7 million years ago
Ardipithecus ramidus - 5 to 4 million years ago
Australopithecus afarensis - 4 to 2.7 million years ago
Australopithecus africanus - 3.0 to 2.0 million years ago
Australopithecus robustus - 2.2 to 1.0 million years ago
Homo habilis - 2.2 to 1.6 million years ago
Homo erectus - 2 to 0.4 million years ago
Homo sapiens - 400,000 to 200,000 years ago
(Homo neandertalensis - 200,000 to 30,000 years ago)
Homo sapiens sapiens - 130,000 years ago to present

Before them, between 5 and 10 million years ago, there was our common ancestor with the apes. This is what is romantically called "The missing link".
Pick one that you want to call the first human, and you will have your answer. I would go with the H habilus. It was here that we first started shaping our environment to make it more comfortable. See link below for more info
