Scientists believe early modern humans originated in Africa. This theory is supported by fossil and genetic evidence that suggests humans evolved in Africa before migrating to other continents.

Birds, which are not just considered descendants of dinosaurs; they are dinosaurs.
Scientists believe that plants evolved on land from green algae, specifically from a group called charophytes. This transition from water to land occurred around 450 million years ago during the Ordovician period.
Scientists believe birds evolved from dinosaurs because of several pieces of evidence, such as shared skeletal features, fossil records of "transitional" bird-like dinosaurs, and genetic similarities. These connections suggest that birds are the descendants of a group of small theropod dinosaurs.
Africa.
Scientists believe that plants evolved directly from a freshwater green algae called charophyte. There are two different types of charophytes, coleochaetales and charales, which strongly resemble earliest land plants.
