However, as the population reaches its maximum (the carrying capacity), intraspecific competition becomes fiercer and the per capita growth rate slows until the population reaches a stable size. At the carrying capacity, the rate of change of population density is zero because the population is as large as possible based on the resources available.

It highlights the importance of checkpoints to prevent errors, which, if present, can lead to chromosomal abnormalities such as monosomy, often lethal, and trisomy, which can result in conditions like Down syndrome.

It highlights how sexual reproduction fosters genetic variation through the fusion of sex cells and meiosis, which reduces chromosome numbers. While asexual reproduction may allow for quicker population growth, sexual reproduction prevails in multicellular organisms due to its evolutionary advantages linked to genetic diversity.

In the first graph, the marginal cost of offspring produced is decreasing (each additional offspring is less "expensive" than the average of all previous offspring) and the marginal cost of offspring forgone is increasing.

It has a genome of approximately 20,000 protein-coding genes and a structured developmental process, where each of its 556 embryonic cells follows a specific lineage, including a predictable apoptosis of 131 cells.
