Are these the same species? How do you know? Are these the same species? How do you know? Are these the same species? In some cases, it is enough to look at two individuals and be able to tell visually that they are different species. But, we should have a better answer! Are these the same species? How do you know? Are these the same species? How do you know? Are these the same species? How do you know? Are these the same species? ● Can they reproduce? ● Are they genetically similar? Are there similarities in their DNA? DNA ● Scientists can extract a DNA sample from the organisms cells that they are hoping to compare. ● In general: the more closely related, the more genetic similarities (= more similarities in DNA). DNA Rank the following. Number 1 will have the most DNA similarities and number 7 will have the fewest ● A human and a chimpanzee (different species) ● Identical twins ● Siblings ● Fraternal twins ● Two unrelated humans ● A human and a shark Reproduction ● Temporal isolation o o Different habitats Mating at different times ● Behavioral isolation o Different mating rituals ● Mechanical isolation Reproduction ● Zygote mortality o Miscarriage ● Non-viability of hybrid o Offspring can’t reproduce Donkey + horse = mule Tiger + lion = liger
