The dodo was variously declared a small ostrich, a rail, an albatross, or a vulture, by early scientists. [3] In 1842, Danish zoologist Johannes Theodor Reinhardt proposed that dodos were ground pigeons, based on studies of a dodo skull he had discovered in the collection of the Natural History Museum of Denmark.
The surprise of evo-devo is that the shaping of bodies is controlled by a rather small percentage of genes, and that these regulatory genes are ancient, shared by all animals. The giraffe does not have a gene for a long neck, any more than the elephant has a gene for a big body. Their bodies are patterned by a system of switching which causes ...

Stupendemys appears in the fossil record as the largest freshwater turtle, first modern elephants, giraffes, zebras, lions, rhinoceros and gazelles appear in the fossil record 3.6 Ma Blue whales grow to modern size. 3 Ma Earliest swordfish. 2.7 Ma Paranthropus evolves. 2.5 Ma Earliest species of Arctodus and Smilodon ...
What a difference a day (or 3.7 million of ’em) doesn’t make. Early on in the premiere of HBO’s Dune: Prophecy prequel series — which is set 10,148 years prior to the Timothée Chalamet ...
Dobo (voiced by Fred Tatasciore) – A Dobermann-type Dog who was a thief and paired with Panthro to earn his freedom from The Pit, eventually becoming the new Pit Master. Upon crossing paths with Panthro after acquiring Pumyra from the Rats, Dobo imprisons Lion-O and takes the Sword of Omens, tellin Panthro that Lion-O can go free if he ...
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]
Carcinisation (American English: carcinization) is a form of convergent evolution in which non-crab crustaceans evolve a crab-like body plan. The term was introduced into evolutionary biology by L. A. Borradaile, who described it as "the many attempts of Nature to evolve a crab". [2]
Charles Darwin first discovered that speciation can be extrapolated so that species not only evolve into new species, but also into new genera, families and other groups of animals. In other words, macroevolution is reducible to microevolution through selection of traits over long periods of time. [ 31 ]
