Geological structures Study guides, Revision notes & Summaries

Sections 2.1 - 2.5 summarize evidence for Evolution. Some evidence had been available to Darwin and his contemporaries, but the majority of the evidence came later, in the 20th century. For example, Darwin was aware of the following: Answer Vestigial structures Geological evidence for mass extinctions Succession in the fossil record Structural and developmental homologies The evidence from biogeography, based on occurrence of closely related species in groups of islands (such as the Galapago...

Biology-B, Unit 1 Exam (2023/2024) Graded A convergent evolution the appearance of apparently similar structures in organisms of different lines of descent homologous structures structures derived from a common ancestor or same evolutionary or developmental origin vestigial structures an anatomical feature that no longer seems to have a purpose in the current form of an organism of the given species evolution the process by which different kinds of living organisms are thought to have develop...
