Charles Darwin is famously known for proposing the theory of evolution by natural selection. He discovered that species evolve over time through processes such as natural selection, which favors traits that offer advantages for survival and reproduction. His ideas were based on observations he made during his voyages, as well as his studies on various plants and animals.

How were embryos important to Darwin's research?

The embryos help Darwin find that finches came from the same ancestor which they go through phases of evolutions, this depends on the island the finches are located. Darwin discover that in different islands the beak from the finches were bigger hence stronger to crack difficult shells from plans, but in a different island finches have smaller beaks to get nectar from that plants. Darwin came to the conclusion that finches adapt from their environment.


Did Darwin have knowledge of DNA when he proposed his theory of evolution?

No, Darwin did not have knowledge of DNA when he proposed his theory of evolution. DNA was not discovered until after Darwin's time, in the 20th century. Darwin's theory of evolution was based on observations of natural selection and the variation and adaptation of species over time.


Foreign scientist inventor of Charles Darwin?

The foreign scientist who influenced Charles Darwin's theory of evolution through natural selection was Alfred Russel Wallace. Wallace independently developed a similar theory to Darwin's, prompting them to present their ideas jointly in 1858. Darwin is credited with the theory of evolution by natural selection, but Wallace also made significant contributions to the field.


How did the ideas of scientists before Darwin influence Darwin ideas?

Scientists before Darwin, such as Lamarck and Lyell, influenced Darwin's ideas by presenting concepts like geology and the idea of species change over time. Lamarck's theory of acquired characteristics and Lyell's principles of uniformitarianism provided a basis for Darwin to develop his theory of evolution through natural selection. Darwin built upon these ideas by incorporating them into his own theory, which became the foundation of modern evolutionary biology.


Was Darwin influenced by Mendels ideas about genetics?

No, Darwin knew nothing about Mendel's ideas and work. His, Darwin's, heritability concept was absolutely wrong. There is a legend that Darwin had a copy of Mendel's work in his desk but could not read German. The veracity of this story is often challenged.
