The evolution of the long-necked giraffe (Giraffa camelopardalis L.)

More about the book

Darwin and various African folk legends suggested that the elongated neck of giraffes evolved to help them reach higher leaves during food shortages. However, this explanation fails to account for size differences between male and female giraffes, as females can be up to 1.5 meters shorter. Additionally, the giraffe's wide migration patterns and the low height of their primary food sources challenge this dominant selection hypothesis. Key issues include: 1) Fossil records show that evolutionary links often coexist rather than replace each other. 2) Similarities used to infer evolutionary relationships rely on circular reasoning. 3) Giraffes possess eight cervical vertebrae, with the eighth exhibiting traits of a neck vertebra, complicating evolutionary narratives. 4) The idea of macromutation leading to long necks is improbable due to complex anatomical structures. 5) Sexual selection lacks a solid mutational basis and can contradict natural selection. 6) Unlike naturalistic theories, intelligent design is testable. 7) Long-necked giraffes may share a common type, as gradual evolution is undermined by vertebral duplication and loss. 8) Chance mutations alone cannot explain the long neck. 9) Intelligent design provides a compelling solution to these issues, supported by ongoing research. 10) While Mitchell and Skinner analyze selectionist problems well, their evolutionary claims remain unproven.
