Evidence that supports the idea of common ancestry includes:
Homologous Structures: This means that different animals have similar body parts. For example, the arms of humans, the flippers of whales, and the wings of bats all have a similar bone structure. This suggests they might come from a shared ancestor.
Genetic Similarities: When we compare DNA, we find that humans and chimps share about 98% of their genes. This shows that we are closely related in terms of evolution.
Fossil Record: Transitional fossils, like Archaeopteryx, show us how species changed over time from common ancestors.
Together, these points show that all life on Earth is connected in some way.
