Study Notes
Behavioral Evolution and Change
- Behavioral change can enhance survival in changing environments.
- Konrad Lorenz identified adaptive behavioral changes occurring through ontogeny and phylogeny.
- Animals possess the ability to acquire and store information from their environment, which aids their survival.
Phylogenetic Change
- Phylogenetic change is defined as alterations that take place across generations within a species.
- Mechanisms of phylogenetic change operate at the individual level, where gene transmission relies on individual reproductive success.
- Phylogenetic changes are dependent on genetic change; genes are only passed on if individuals reproduce successfully.
Ontogeny and Learning
- Ontogeny refers to behavior development within an individual’s lifetime influenced by environmental factors.
- Learning, a part of ontogeny, leads to age-independent behavioral changes that are vital for survival.
- Maturation involves the gradual development of physical structures and age-related behavioral adjustments; certain developmental milestones, like walking or talking, are reached at specific ages.
Great Apes Taxonomy
- Great apes include chimpanzees, bonobos, gorillas, orangutans, and humans, all classified in the family Hominidae.
- Hominidae consists of two subfamilies:
- Ponginae, which includes orangutans (genus Pongo).
- Homininae, which includes gorillas (genus Gorilla), common chimpanzees (genus Pan), and humans (genus Homo).
Evolutionary Relationships
- Chimpanzees share a closer genetic relationship with humans compared to other great apes.
- Gorillas are more closely linked to chimpanzees and humans than to other ape species.
- The inferred evolutionary lineage is: orangutans (genus Pongo), gorillas (genus Gorilla), chimpanzees (genus Pan), and humans (genus Homo).
Molecular Clock Insights
- The separation of the chimpanzee lineage from humans is estimated to have occurred between 678-116 million years ago.
- Median date for this divergence is estimated at around 665 million years ago, with a variation of 623-707 million years ago based on molecular studies.
Great Apes Care in Zoos
- Non-human great apes exhibit genetic, anatomical, and cognitive similarities to humans.
- It is crucial to provide these animals freedom of choice regarding their environment and care practices.
Orangutans
- There are two species of orangutans: Bornean and Sumatran, with a new third species, Tapanuli orangutan.
- Tapanuli orangutan is only found in North Sumatra and Tapanuli region.
- Understanding species and sub-species taxonomy is vital for releasing rescued orangutans in their natural habitats.
Morphological Differences in Orangutans
- Bornean orangutans have wider, figure-8-shaped faces and pronounced facial features in mature males.
- They possess larger, more pendulous cheek pouches than other species, impacting their behavior in captivity.
- Sumatran orangutans feature longer, oval faces and possess distinctive face hair, such as beards and mustaches.
Reproductive Development in Male Orangutans
- Male orangutans can begin reproducing as early as 10 years, particularly under captive conditions.
- Some males may not achieve full physical maturity, such as developing cheek flanges, a phenomenon referred to as "developmental arrest."
- Even immature males can still reproduce, and if a dominant male is removed from an area, it can lead to increased reproductive activity in adolescents.
Evolutionary Species Concept
- According to the Evolutionary Species Concept, different species exhibit heritable differences despite the lack of interbreeding.
- DNA analysis suggests a separation of approximately 1.2 million years between Bornean and Sumatran orangutans, varying based on different studies.
