Thank you Luisa for your second question. Here are my friends thoughts about how humans appeared.
Thanks team, Luisa let me add some more details.
My friends are correct, it is thought that the first life appeared millions of years ago. The life that formed was not at all like the animals and plants that we see around today. It was very, very small. So small that we would have needed a microscope to see it. Over the next thousands of years that life changed (we say it evolved) and it reproduced. Sometimes when it reproduced mistakes were made and bigger forms of life were formed. Eventually a mistake in the reproduction led to the first plant (a moss) being formed.
Over the next thousands of years further mistakes were made and the first animal was born. From then onwards the evolution of animals and plants continued…….UNTIL …..again many thousands of years ago the first apes evolved. The apes continued to have babies and further mistakes were made …… the baby apes walked upright, their brains were bigger, they had less hair, all small changes but over thousands of years small changes can become big changes. The result was that humans were formed and you, me and everybody else are the result.
Things haven’t stopped ….changes (evolution) continues …..we might be very different in many thousands of years time.
Hope this helps. Not happy about something, then ask another question.
