Ancient DNA refers to genetic material extracted from the remains of organisms that lived in the past, providing insights into evolutionary history, migration patterns, and species interactions. Advances in sequencing technology have enabled the recovery and analysis of ancient DNA, despite challenges posed by degradation and contamination over time.

Ancient DNA

Genetic material is the molecular basis of inheritance, encoding the information necessary for the development, function, and reproduction of living organisms. It primarily consists of DNA and RNA, which carry genetic instructions in the form of sequences of nucleotides.

Evolutionary history refers to the study of the origin and development of species over time, tracing their genetic and morphological changes through successive generations. It provides insights into the mechanisms of natural selection, adaptation, and speciation, helping us understand the diversity and complexity of life on Earth.

Evolutionary History

Migration patterns refer to the regular, often seasonal movement of species from one location to another, driven by factors such as climate, food availability, and breeding needs. Understanding these patterns is crucial for biodiversity conservation, managing natural resources, and predicting the impacts of climate change on ecosystems.

Migration Patterns

Species interactions are the various ways organisms in an ecosystem affect each other's survival and reproduction, shaping community dynamics and ecosystem functions. These interactions can be beneficial, harmful, or neutral, and include competition, predation, mutualism, commensalism, and parasitism, each playing a crucial role in maintaining ecological balance.

Recovery and analysis of ancient DNA

DNA degradation refers to the breakdown of DNA molecules into smaller components, often caused by environmental factors, enzymatic activity, or chemical reactions. This process is significant in fields like forensic science, molecular biology, and biotechnology, where DNA integrity is crucial for accurate analysis and applications.
