DNA analysis helps scientists better understand evolution in several ways:
1. By comparing the DNA sequences of different organisms, scientists can infer evolutionary relationships and construct phylogenetic trees to show how different species are related to each other.
2. DNA analysis can also reveal genetic mutations that occur over time, providing evidence for how species have evolved and adapted to their environments.
3. DNA analysis can help identify genes that have been conserved throughout evolution, giving insights into important biological functions and processes that have remained relatively unchanged over time.
4. By studying changes in DNA sequences, scientists can also gain a better understanding of how species have diverged from a common ancestor and evolved over millions of years.
Overall, DNA analysis is a powerful tool that allows scientists to study the genetic basis of evolution and gain insights into the mechanisms driving the diversity of life on Earth.
How does DNA analysis help scientists better understand evolution?
It shows us what codons an organisms has.
It spells out the amino acids that make up an organism.
It helps chart changes in amino acid sequences over time.
