Summary Introduction
Introduction:
The shared evolutionary ancestry can be reflected by similarity in biological molecules such as all mammals contain DNA as their genetic material. Two or more species can contain the same gene as they have inherited from a common ancestor.

DIRECTIONS: Complete the paragraph about evidence of evolution by choosing the correct word provided below. biogeography fossils homologous molecular vestigial The theory of evolution states that modern species have descended from ancestral species through evolution and speciation. It is supported by a large body of evidence such as found in geologic strata. These are remnants of ancient life that provide evidence for the evolutionary change through now-extinct forms that led to modern species. Modern species retain certain structures that arose from a common ancestor structures. Other remnants of what was once useful to the ancestors are or the findings of the original distribution of related species across the Earth the connections between ancient evidence, DNA sequences have also shed light on the occurrence of such as structures. Furthermore, we can infer from the landmasses.

- Please help with the following prompt using as much details as possible. "One argument that is often made to invalidate evolution by natural selection is that some features of an organism are so complicated and need to work together in order to precisely function that it is impossible for such structures to arise from simpler ones by the random processes of mutation and selection: complicated design requires a designer. Using evidence from real organisms, explain how a complicated structure can arise from a simpler ancestral feature. You can use either an anatomical feature or molecular one."arrow_forwardThe tail flukes of a whale are _________to the tails of fish- they are not anatomically the same but evolved due to similar selection pressures.
