- In evolutionary developmental biology, heterochrony is defined as a developmental change in the timing or rate of events, leading to changes in size and shape. There are two main components, namely (i) the onset and offset of a particular process, and (ii) the rate at which the process operates. A developmental process in one species can only be described as heterochronic in relation to the same process in another species, considered the basal or ancestral state, which operates with different onset and offset times, and at different rates. The concept was introduced by Ernst Haeckel in 1875
NEOTENY : The retention by adults of traits previously seen only in the young is important in developmental biology, and consequently in evolution. It occurs in two ways. In neoteny also called juvenilization the physiological (or somatic) development of an organism (typically an animal) is slowed or delayed. Neoteny is found in modern humans
n contrast, in progenesis (paedogenesis), sexual development occurs faster.[7] Both processes result in paedomorphism (or paedomorphosis), a type of heterochrony. Some authors define paedomorphism as the retention of larval traits, as seen in salamanders
Accent was hard to understand but the info was absolutely great. I’m happy that folks are out there making videos like this
Whoa! Amazing explanation.Now everything is just Crystal clear.

Pedogenesis is the formation of soil.. .. .? ?? ?
You didn't explain Paedogenesis, you just mentioned that in the title and said one sentence about it in the video.
Will consider making seperate video for Paedogenesis....
Neogeny and PROGENESIS are two forms of Paedomorphism
Are you a Kashmiri? Just wanted to ask coz your are speaking just like my friend who is also a Kashmiri.😊
Yes.. I am Kashmiri.😊😊
@@hussainbiology haha it's been 2 years of my friendship with a Kashmiri....gotch u😁 keep up the good work..god bless you.
thanks for appreciation...Glad to know that it helps ✌️

This is basically saying that semen retention for a certain amount of prolonged time manifests in a highest capacity of human characteristics of new born human when the retained semen is finally secreted for the purpose of nature
What? No that is not at all what it is about. It is not a choice, even if you retain seamen.

It is supposed to be pedomorphosis
Neogeny and PROGENESIS are two forms of Paedomorphism
Booooo👎👎👎
