The two properties that a human and a spider would exhibit is that both of them are composed of eukaryotic cells and the exhibit sexual reproduction. Eukaryotic cells are cells with membrane bound organelles such as the nucleus which contains the genetic material enclosed by a nuclear membrane. Sexual reproduction is a type of reproduction where livings give rise to new off springs by combining genetic material from two individuals of different sexes.
While humans and spiders are very different, they both share several common properties. One such property is that they both have eyes to help them see. Another property is that they are both classified as living creatures.
