How do scientists determine the evolutionary relationship among species?
They use a taxonomic map to help classify organisms. The placement of organisms on this was originally based on similarities between species. Today we are able to look at their actual genes, which has resulted in a better understanding of evolutionary relationships - or the lack of them- and has resulted in some re-classification.
Why is DNA used as evidence in natural selection?
Mathematical analysis in genetics and comparative genomics can show scientists to what degree a particular genetic sequence resulted from selection pressures at a given time in the evolutionary history of the organism under consideration.
Where do people came from originally?
Scientists believe that modern humans evolved in Africa around 300,000 years ago. From there, Homo sapiens migrated and spread out to different parts of the world. This process of human migration and evolution has resulted in the diverse populations and ethnicities we see today.
When food and water became hard to find early scientists split apart is that true or false?
True. Early scientists often faced challenges in securing food and water during their explorations and experiments, which could lead to divisions within their groups. These hardships sometimes resulted in disagreements over priorities and methodologies, causing collaboration to break down. Such conditions were particularly evident in prolonged expeditions where resources became scarce.

In 1942 American scientists began developing a superbomb?
In 1942, American scientists began developing a superbomb. It was called the Manhattan Project and resulted in the construction, testing and deployment of the atom bomb on Japan in 1945.
What were the results of the project?
The Manhattan Project resulted in the first atomic bombs. The research for this took place from 1942-1945 and was done by a number of scientists and engineers.
