Here is a couple paragraphs with quite a few of the early, basic words common to several languages:

2.Who were the Indo-Europeans?
1.What can we learn from their language?
1.common words for snow, winter, spring; for dog, horse, cow, sheep bear but not camel, lion, elephant, or tiger; for beech, oak, pine, willow, but not palm or banyan
2.I-E Cultural: complex sense of family relationship and organization; used gold and silver but not copper and iron; words for "wheel," "axle," and "yoke" show they used animals to pull wheeled vehicles; they
farmed (not nomadic) with plows and kept domestic animals; they believed in multiple gods.
2.The bee problem
1.Many I-E languages have cognates for the honey bee and for a fermented honey drink (e.g. Greek "méli" (honey) and "mélissa (bee); Latin mel (honey); Old English milisc (honey sweet), medu (mead) and mildeaw (honey dew); Sanskrit madhu (honey); Dutch mede)
2.Bees are not found in any of the Asiatic sites proposed as the IE homeland.
