A common ancestor.
Physiological similarities suggest the species evolved from the same ancestor.
Physiological similarities suggest the species evolved from the same ancestor.
Fossil records of identical species found on different continents. Geological similarities in rock formations across continents. Matching coastlines and mountain ranges on opposite sides of continents. Distribution of similar species across continents, indicating they were once connected.
Comparative psychologists study behavioral similarities and differences between species. They focus on understanding how behaviors have evolved across different species and how they are influenced by environmental and genetic factors.
In addition to matching coastlines, Wegener used similarities in rock formations and mountain ranges across different continents as evidence for his theory of continental drift. He also noted similarities in the distribution of fossils on separate continents, suggesting that the same species were once connected when the continents were joined.
It's called convergent evolution. Where two species that are separated by a barrier evolve similar structures or behaviors. This is because they most likely live in similar environments that cause them to adapt similar features to survive in that particular environment.
Anatomical similarities among different species provide evidence of evolution through the presence of homologous structures, which are structures that have a common evolutionary origin. These similarities suggest that different species share a common ancestor and have evolved from it over time, resulting in variations in the form and function of these structures. By comparing anatomical features across species, scientists can infer evolutionary relationships and trace the evolutionary history of organisms.
Biochemical similarities among different species, such as shared genetic sequences and metabolic pathways, provide evidence for a common ancestry and evolutionary relationships. These similarities suggest that organisms have evolved from a common ancestor and have undergone genetic changes over time. Studying biochemical similarities helps scientists understand the processes of evolution and how species have diversified and adapted to their environments.
Actually yes it can. Embryos, DNA sequences, and fossils amongst others things can help show similarities within species. This can show that those species have similar traits because they evolved from a common ancestor. But those differences show why they are different species and thus evolving.
When the continent separated some of the same species ended up on different continents. This is because the continent was so large the species were distributed across the continent. So, when it split, some were on one side and others of the same species were on the other side.
Alfred Wegener presented several lines of evidence to support his theory of continental drift, including the fit of the continents like a jigsaw puzzle, similarities in rock formations and mountain ranges across continents, and the distribution of fossils of the same species on different continents separated by oceans.
Alfred Wegener used evidence such as the fit of the continents, matching geological formations across continents, identical fossil species found on different continents, and similarities in rock types and mountain ranges as support for his theory of continental drift.
