The geographic distribution of the swimming reptile Mesosaurus provides evidence that supports continental drift. Fossils belonging to the Mesosaurus were found far away from each other, in both South Africa and South America.
South america and Africa were once joined.
The case of Mesosaurus does support the theory of continental drift, particularly in the context of plate tectonics. This freshwater reptile's fossils were found in both South America and Africa, which are now separated by the Atlantic Ocean. The presence of such a species in these two distant locations suggests that the continents were once joined, allowing Mesosaurus to inhabit both regions. Thus, it provides evidence against the idea that these continents have always been in their current positions.
Data from the study of biogeography provides evidence for evolution by showing patterns of species distribution that can be best explained by common ancestry and adaptation to different environments. It helps in understanding how species have evolved and diversified over time in response to changes in their habitats and geographic isolation. By studying the distribution of species in different regions, scientists can infer evolutionary relationships and historical connections between organisms.
The range or area occupied by a population is called its habitat. A habitat provides the resources and conditions necessary for a population to survive and thrive. It includes the physical environment, such as food, water, shelter, and breeding sites.
Evidence for evolution leading to the development of modern species includes the fossil record showing transitional forms, genetic similarities between species, geographic distribution of species, and the observation of natural selection in action. These pieces of evidence support the idea that species have changed over time and continue to do so through the process of evolution.
Fossil distribution provides compelling evidence for the theory of continental drift by showing that identical species of plants and animals have been found on widely separated continents, such as South America and Africa. For instance, the discovery of the Mesosaurus, a freshwater reptile, in both South America and Africa suggests these continents were once connected, allowing the species to inhabit both regions. This pattern of fossil distribution indicates that continents have moved over geological time, supporting the idea that they were once part of a larger landmass before drifting apart.
A linguistic distribution map shows the geographic locations where different languages are spoken. It provides a visual representation of the distribution of languages across regions or countries. The map helps illustrate the diversity of languages and their patterns of usage in different areas.
Geographic distributions refer to the patterns of where a species is found in a geographical area. It provides insight into the range, abundance, and habitat preferences of a species. Geographic distributions can be influenced by factors such as climate, habitat availability, and interactions with other species.
All organisms are adapted to their environment to a greater or lesser extent. If the abiotic and biotic factors within a habitat are capable of supporting a particular species in one geographic area, then one might assume that the same species would be found in a similar habitat in a similar geographic area, e.g. in Africa and South America. This is not the case. Plant and animal species are discontinuously distributed throughout the world

The fit of the continents' coastlines, identical rock formations and mountain ranges on different continents, and the distribution of similar fossils on separate landmasses are all evidence supporting the theory of continental drift and the existence of the supercontinent Pangaea.
A change in position is evidence that motion happened.
