Which of the following is NOT an evidence for Darwin's theory of common descent? Group of answer choices Due to innate drive to improve, parts that are extensively used becomes larger and stronger and passed on to the next generation as seen on fossil records. Anatomical structures, such as forelimbs, in different groups appear to be modified versions of structures that might have been present in a common ancestor. There are biogeographic patterns in the distribution of species, for instance distinct bird species on an island tend to resemble one another, suggesting a common ancestor. There are common stages in the early embryological development of organisms representing several distinct vertebrate groups.
Which of the following is evidence that supports Darwin's theory of common descent? (Choose all that apply) There are patterns in the fossil record that suggest some species have diverged from a single ancestral species There are biogeographic patterns in the distribution of species, for instance, distinct bird species on an island tend to resemble one another, s ancestor There are common stages in the early embryological development of organisms in several distinct vertebrate groups. Anatomical structures, such as forelimbs, in different groups appear to be modified versions of structures that might have been present in a co Similar anatomical features in different organisms always indicated close common ancestry
Characteristics like the panda's "thumb" and the seven long bones in a giraffes neck show us that; Evolution is goal oriented There could indeed be a perfect organism that evolves some time in the future Evolution leads to imperfect adapations The phyletic gradualism model of speciation is most likely correct
What was the most important idea of Lamarck's theory of evolution that contributed to Darwin's theory? Organisms could be grouped according to similarity. Selection could operate on individuals, instead of on species as a whole. O Within a species, there was lot of variation between individuals. Individuals could change in response to the environment, and this acquired trait was passed on. Indoor Playgrow W

The theory of evolution by Darwin is a composite theory, i.e. it has five component theories: 1. Evolution as such is the simple proposition that the characteristics of lineages of organisms change over time 2. Common descent is a radically different view of evolution than the scheme Lamarck proposed. Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. 3. Gradualism – Darwin’s proposition that the differences between even radically different organisms have evolved incrementally, by small steps through intermediate forms. The alternative to this theory, as discussed in later sections, is saltation with great reference to large differences that are believed to have evolved by leaps without intermediates. 4. Populational change – Darwin’s thesis that evolution occurs by changes in the proportions of individuals within a population that have different inherited characteristics. 5. Natural selection – Darwin’s…
