מדרש על שבת 61:1

Rabbi Tanchuma said in the name of Rabbi Eliezer and Rabbi Menachem in the name of Rav said, "Adam taught all the craftsmen, as it says, 'And the craftsmen, they are adam-ic,' (usually, 'merely human,' Isaiah 44:11) i.e. they are from Adam." The Rabbis taught: "Even the ruling of manuscripts, Adam taught, as it says, 'This is the book,' i.e. it and its ruling, and continues, 'On the day that God created Adam;'" (Genesis 5:1) this accords with that which Rabbi Elazar b. Azaryah said, "Three wonders did God do on that day: On that day he created him, on that day he attended him, and on that day he gave him offspring." Ben Azzai said: “These are the generations of Adam" (Genesis 5:1) is a great principle in the Torah. Rabbi Akiva said: "This is a great principle of the Torah: 'You shall love your neighbor as yourself,' (Lev. 19:18). meaning that one should not say, 'Since I am scorned, I should scorn my fellow as well; since I have been cursed, I will curse my fellow as well.'" Rabbi Tanchuma says, “If you do this -- know that God made the person you put to shame in His own image."
