paleontologists are still debating about whether modern behavior, language, and art appeared more recently in europe, about 50,000 years ago or further back, based on findings such as the tools and artifacts found at the blombos cave. what do you think? do you think the artifacts show higher level thinking, or just a form of art? explain your answer.

cad, or computer-aided design and drafting (cadd), is a software for design and technical documentation, which is an automated process as opposed to the manual drawing of plans. this gives a person an advance in making plans as an architect in a short period of time. one who can render plans through this software will gain a skill that is better than one who makes plans manually. this is a skill some companies look for in an employee.
