Salutations! would you kindly me out on this question? the diagram shows embryo development of four different animals. how is this evidence to sugest that life changes over time? a: stiking similarites at early developmental stages is evidence that they came from a common ancestor. b: late-stage embyronic development illustrates how aacquired characteristics have caused these to become more differentiated over time. c: these stages indicate that animals within a species must have changed over time. d: the dna of all these life forms begins exaclty the same and then changes over time as it replicates to produce the orgainsms different traits

What is one function of the embedded proteins

And give a detailed description! scientist observes the boundary between two tectonic plates for a decade and finds that no new volcanoes have formed over the course of her investigation. does this result support the theory of plate tectonics? why or why not?

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
