: Many marine species change sex during their lifetime.
: The ratio of adult males to females in a population (Adult Sex Ratio) often dictates maturation timing. Male-skewed environments may cause females to mature later, and vice versa. 2. Maturation in Specialized Sexual Systems sex matures
Differences in maturity age can lead to skewed sex ratios on spawning grounds; if one sex matures later, fewer individuals survive the return migration. 4. Human Development and Invariance
Some organisms do not have fixed sexes throughout their lives, leading to complex maturation patterns. : Sex hormones and maternal effects play a
: Individuals mature first as females and later transition to males.
: In many species, intense competition for mates can lead to delayed maturation in the sex facing higher selection pressure. For example, in some bird populations, males mature later than females to reach a size or social status necessary for successful competition. Male-skewed environments may cause females to mature later,
: Individuals mature first as males and later change into females.
