In summary, neoteny and post development are two terms used to describe the timing of reproductive maturation in organisms. Neoteny refers to the early maturation of gonads in larvae, which then stops growing and does not reach adult development. On the other hand, post development refers to a delay in the onset of developmental processes relative to reproductive maturation, implying eventual development. While they may seem similar, neoteny specifically includes the aspect of never reaching adult development, while post development does not.

what is the difference between neoteny and post development

according to my lecture
neoteny = early maturation of gonads in larva that then stops growing and never becomes an adult

post development = onset of a developmental process is delayed relative to reproductive maturation

...they sound like the same thing...are they the same thing or is there a difference. i have done a google search on this, but can't seem to find any results. any help towards clarification would be appreciated. thanks

Well, I'm no biologist but based on what you wrote, the definition of "neotany" includes "then stops growing and never becomes an adult" which "post development" does not - it implies eventual development.
 

1. What is neoteny and post development?

Neoteny and post development are two concepts related to the process of growth and development in organisms. Neoteny refers to the retention of juvenile characteristics in adults, while post development refers to the stage of development after an organism has reached sexual maturity.

2. What are examples of neoteny and post development in animals?

An example of neoteny is the retention of gills in the axolotl, a type of salamander. An example of post development is the growth of antlers in male deer after reaching sexual maturity.

3. How do neoteny and post development affect an organism's physical characteristics?

Neoteny can result in physical characteristics such as a smaller body size, larger eyes, and a flatter face. Post development can result in physical characteristics such as increased muscle mass, changes in fur or feather color, and the development of secondary sexual characteristics.

4. What is the evolutionary significance of neoteny and post development?

Neoteny and post development can both play important roles in an organism's evolutionary process. Neotenic traits can allow for extended periods of learning and adaptability, while post development can aid in attracting mates and competing for resources.

5. How are neoteny and post development studied in scientific research?

Scientists study neoteny and post development through a variety of methods, including observing physical characteristics and behaviors of organisms, analyzing genetic and developmental pathways, and comparing different species. They also use techniques such as hormonal manipulation and genetic modifications to study the effects of neoteny and post development on organisms.
