Evolution on Earth has not stopped. It is an ongoing process driven by factors such as natural selection, genetic mutation, and environmental changes. Organisms continue to adapt to their surroundings, leading to changes in populations over time.

Scientists believe that Australopithecus afarensis became extinct due to a combination of factors such as changing environmental conditions, competition for resources with other species, and potential predation pressure. The inability to adapt to new ecological challenges may have also contributed to their extinction.
Genetic variation and environmental factors are the two main factors that cause individuals of the same species to appear different. Genetic variation results from differences in DNA sequences passed down through generations, while environmental factors such as diet, climate, and exposure to sunlight can also influence physical appearance.
Scientists now think that the pace of evolutionary change can vary greatly depending on factors such as environmental pressures, population size, and genetic variation. It is understood that evolution can occur rapidly in response to sudden changes in the environment, while in stable conditions, evolution may proceed at a slower pace. Additionally, new research suggests that evolution can also occur in punctuated bursts rather than consistently over time.
Charles Darwin is primarily associated with the theory of evolution through his work on natural selection and the publication of "On the Origin of Species." Other scientists, such as Alfred Russel Wallace, also contributed to the development of evolutionary theory.
Scientists are interested in studying the rate of evolution because it provides insights into how species have changed over time. By understanding the pace at which genetic variations accumulate in populations, researchers can better comprehend the mechanisms driving evolution and its impacts on biodiversity. The rate of evolution can also inform predictions about how species might respond to environmental changes.
Tom Sever, an archaeologist, suggests that a combination of factors led to the downfall of the Mayan civilization, including environmental degradation, climate change, warfare, and political instability. He believes that these issues created a perfect storm that ultimately contributed to the collapse of the Maya civilization.
