Did humans evolve from reptiles?
No, humans did not evolve from reptiles. Both humans and reptiles share a common ancestor from millions of years ago, but they evolved along separate paths.
Is one million years sufficiently long to be considered a period of geologic time?
Yes, one million years is a significant period in geologic time. It is equivalent to 1/485th of the age of the Earth (4.54 billion years). In the geologic time scale, it falls within the Quaternary period, which includes the most recent 2.6 million years of Earth's history.
Did we evolve from ancestors who had tails"?
Yes, humans evolved from ancestors who had tails.
Which would evolve faster humans or bacteria?
Bacteria would evolve faster than humans due to their shorter generation times and larger population sizes, allowing for quicker adaptation to environmental changes and mutations to occur. Humans have longer generation times and smaller population sizes, slowing down the rate of evolution.
Did humans evolve?
All organisms, including humans, have evolved from ancestral organisms and continue to evolve, although at a rate too slow to witness during one lifetime.
How do humans relate to geologic time scale?
in the scope of geologic time, how significant is the presence of humans?
Is A geologic era is a shorter unit of time than a geologic period?
No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
What period represents the last 2 million years of geologic time?
The last 2 million years of geologic time is part of the Quaternary Period, which is characterized by major advances and retreats of continental ice sheets, as well as the evolution and dispersal of humans.
What is the division of geologic time you live in today?
We live in the Cenozoic era. Currently, we are in the Holocene epoch of the Quaternary period. Humans evolved in the Pleistocene epoch which was also in the Quaternary period.
What geologic scale are humans in?
Cenozoic
When do scientists think that humans first appeared in the geologic time scale?
Scientists believe that humans first appeared during the Quaternary period, specifically in the Pleistocene epoch. This period started about 2.6 million years ago and continues to the present day.
What geologic time scale are humans in?
Cenozoic
What geologic time period did the crylophsaurus live?
the Jurassic Period
Who are the heroes in the prehistoric period?
The tiny tribe(s) that survived against almost impossible odds to evolve into humans.
Scientists think humans first appeared in the of the geologic time scale?
Humans
Middle division of geologic time?
Period.
What is the geologic time period of the octopus?
Cenezoic
