To their surprise, their offspring had adapted to forest life remarkably well; the children's white headdresses had dissolved into fur, tails grew from their spines and they refused to come home.
Whereas the likely adaptive value of self-compatibility is the assurance of reproduction when pollinator populations are unpredictable [ 31, 32], outcrossing permits the production of variable offspring with adapted genotypes, which is considered particularly important for colonizing species in unpredictable environments [ 26, 33, 34].
Immigrants and their offspring must adapt to French rules, not the other way round.
His thoughts on lifespan, asexual reproduction and sexual reproduction developed in his "B" notebook around mid-July on to variation in offspring "to adapt & alter the race to changing world" explaining the Galápagos tortoises, mockingbirds and rheas.
In addition, we see that fitness differences between hybrids (offspring from parents adapted to different niches) and non-hybrids (offspring from parents adapted to the same niche) are small and decrease over evolutionary time.
Let us further make the plausible assumption that matings between two different specialists result in offspring with lower fitness, since these offspring are not adapted to any of the niches.
Furthermore, if mothers exhibited preferences for particular characteristics of their redd, the use of artificial nests could miss aspects of offspring adaptation to the specific incubation conditions locally adapted mothers usually create for them.
But the reason that they have better adapted offspring is that they have passed on more advantageous features to the next generation.
Thus, the more closely the patterns of maternal care predict the challenges of the adult environment, the better the offspring will be adapted to adult life conditions.
It has been proposed that the emergence of the placenta allowed for longer gestation periods resulting in the live birth of larger better adapted offspring (Romer 1967).
