Half a century before Albert Einstein, English naturalist Charles Darwin's scientific theory of evolution by natural selection founded modern evolutionary studies.
Between the 1890s and 1910s was a period of widespread social activism and political reform across the United States of America.
When the book was published in 1859 it became a bestseller instantly, partly thanks to his conversational style in the book, rather than academic.
The identification of signatures of adaptations to such dietary changes in the human genome sheds light on the evolutionary history of our species? metabolism.
Evolutionary theory does not say any given species can evolve into totally different species. Evolution is about the accumulation of slight changes in new generations of species.
The English biologist discovered the fact that species better adapt to their environment over time by developing, modifying, repurposing, and losing inheritable characteristics. However, Darwin did not understand the mechanism behind how species change. What Darwin did not know was genes and subsequently their mutation.
Some of the most exciting discoveries in evolutionary biology in recent years have shown how humans have adapted to extreme conditions, such as living at high altitudes. Now, researchers have found that Indonesia's Bajau people, who for generations have spent the majority of their days diving and hunting underwater, also have genetic adaptations for their unusual lifestyle. These "sea nomads" carry a gene variant that seems to lead to unusually large spleens that can supply an extra boost of oxygenated red blood cells on demand.
As a species, humans have populated almost every corner of the earth. We have developed technologies and cultures which shape the world we live in.
Charles Darwin is the first human who made people aware of their place in the evolutionary process, which directly or indirectly helped develop many scientific and humanist ideas
