Why do body structures of some species support Darwin's theories?
a cell can make mistakes when it copies what in the dna
Did Darwin use DNA or other genetic information in deveolping his theory?
No, Charles Darwin did not use DNA or genetic information in developing his theory of evolution. Darwin formulated his ideas based on observations of natural selection, variation among species, and fossil evidence during his voyages in the 19th century. The understanding of genetics and DNA emerged later, particularly with the work of Gregor Mendel in the mid-1800s and the discovery of DNA's structure in the 20th century. Darwin's theories were foundational for evolutionary biology, but they predate modern genetic science.
How does DNA support Darwin's theory of descent with modification?
DNA contains the genetic information that determines an organism's traits. Through mutations and genetic variations, DNA can change over time, leading to differences in traits among individuals within a population. This supports Darwin's theory of descent with modification, as it provides a mechanism for how species can evolve and adapt to their environment over generations.
Did Darwin know about DNA?
No
Why do the body structures of some species support Darwin' s theories?
a cell can make mistakes when it copies what in the dna
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.
Charles Darwin's development of DNA?
yes.

After Darwin returned to England what hypothesis did Darwin develop to explain his findings?
He developed main streams of DNA.
What are the methods of preparing DNA for forensic analysis?
DNA for forensic analysis is typically prepared using methods such as DNA extraction from biological samples, quantification of DNA concentration, amplification of specific DNA regions using PCR, and analysis of the DNA profiles through techniques like gel electrophoresis or DNA sequencing. Additionally, DNA samples are often treated with chemicals to remove contaminants and prevent degradation before analysis.
What discovery in the 1900s suppoprted mendels ideas?
The discovery of DNA in the 1950s provided strong support for Mendel's ideas on inheritance. Understanding that genes are made up of DNA and that they are passed down from parents to offspring helped to confirm Mendel's principles of heredity.
What unifying them brought the work of mendel and and Darwin together in the big picture of biology?
The unifying theme that united the work of Darwin and Mendel was the discovery of DNA. DNA stands for Deoxyribonucleic acid.
