  1. 3. A change in the DNA sequence that can lead to genetic variation within a population.
  2. 4. The evolutionary process by which new biological species arise
  3. 5. An early hominid species that lived between 3.9 and 2.9 million years ago. Famous for the discovery of "Lucy," a well-preserved skeleton, this species walked upright but still had some adaptations for tree climbing.
  4. 8. Hommo Specie which inhabited Earth until 40000 years ago
  5. 12. process through which species undergo genetic change over time, leading to the diversity of life.
  6. 15. The most recent ancestral form or species from which two different species evolved.
  7. 16. The transfer of genetic material between populations, which can affect genetic variation.
  8. 18. A hominid species that lived between 3 and 2 million years ago in Africa. They had a combination of ape-like and human-like features, including a smaller brain but bipedal locomotion.
  9. 20. The mechanism by which individuals better adapted to their environment tend to survive and reproduce more successfully.
  10. 21. A small hominid species discovered on the Indonesian island of Flores, living about 100,000 to 60,000 years ago. Known as the "Hobbit" due to their short stature and small brain size.

  1. 1. A species that lived between 600,000 and 200,000 years ago and is considered a common ancestor to both Neanderthals and modern humans. They had a larger brain and were capable of building shelters and hunting large animals.
  2. 2. A phrase often associated with natural selection, describing how organisms best adapted to their environment are more likely to survive.
  3. 6. The British naturalist who independently conceived a theory of evolution through natural selection and co-published with Darwin.
  4. 7. A mechanism of evolution involving random changes in the frequency of alleles in a population.
  5. 9. naturalist who developed the theory of evolution by natural selection, author of "On the Origin of Species."
  6. 10. Name of the first human known to craft tools
  7. 11. The species name for modern humans. Characterized by a high forehead, rounded skull, smaller teeth, and a prominent chin. They are known for their complex language, culture, and technological advancements.
  8. 13. The study of the evolutionary relationships among biological species based on genetic or physical characteristics.
  9. 14. An extinct species that lived from about 1.9 million to 110,000 years ago. They were the first to have human-like body proportions and to use fire and more complex tools. Their name means "upright man.
  10. 17. The history of life documented by fossils, providing evidence of past organisms and their evolution.
  11. 19. A trait that enhances an organism's ability to survive and reproduce in its environment
