Olfspring must be similar to their parents due to shared genes. Discuss at least four characteristic traits of primates that other mammals do not share. To account for these and other issues, biologists and palaeontologists use a whole raft of different 'species concepts' that can help separate species from one another and also identify new species. No, species do not change even after many generations, so individuals of the same species would not look different. For example, chimpanzees and humans, the skulls of which are shown in Figure 12.2. Which of the following is REQUIRED for the process of evolution by natural selection to occur? Why does diversity between individuals and between species create problems for determining what is a species and what is a variant?
