Most of the DNA sequence differences between species that diverge from each other do not involve significant changes in the protein-coding sequences of the genome, but rather, in the cis regulatory sequences of genes (enhancers). Describe two examples from this course which demonstrated this idea. WHY does evolutionary change through changes to the regulatory sequences provide an advantage over changes made to the protein-coding sequences of genes?

Hair follicles initially form during development via reciprocal interactions between the epidermis and dermis, initiated by the [answer1] signaling pathway. The cells of the dermis make the [answer2], a clump of cells that induces the proliferation of hair-forming cells. [answer3] cells contribute pigment to the hair. The stage of the hair cycle in which the hair follicle starts to recede in length as it stops growing new hair is called [answer4].

At the beginning of 2025, Pitman Co. purchased an asset for $1,800,000 with an estimated useful life of 5 years and an estimated salvage value of $150,000.
