Understanding the mechanisms underlying speciation remains a challenge in evolutionary biology. The adaptive radiation of Darwin’s finches is a prime example of species formation, and their study has revealed many important insights into evolutionary processes. Here, we report striking differences.

Apr 06, 2018  · There’s no such thing as an evolutionary dead end. You may be thinking about the fact that sponges closely resemble the ancestors of all multicellular animals (they are ‘primitive’, to use the somewhat misleading technical term). That’s true, but it doesn’t make them a dead end.

Basically, species with lots of features in common are likely to. reproductive biology of placoderms becomes one of the specialisations of this evolutionary dead end. To most biologists, the latter.

Jun 12, 2018  · Evolutionary dead ends — infertility, deadly genetic diseases, poor immunity, etc. — continue to exist in our population partly because modern medicine and technology have bypassed the role of natural selection by allowing these individuals to survive and lead long and meaningful lives when evolution would have dictated otherwise.

This work confirms that this species is among the oldest known living lineages of asexual animals. The research also explains how this worm has evaded the dead end that asexual organisms usually see.

The Ancestor’s Tale: A Pilgrimage to the Dawn of Life is a 2004 popular science book by Richard Dawkins, with contributions from Dawkins’ research assistant Yan Wong. It follows the path of humans backwards through evolutionary history, meeting humanity’s cousins as they converge on.

To researchers, the size of the fruit is all the more remarkable because it is an evolutionary dead-end for the palm. The heavy seed hampers the plant’s dissemination significantly, as the ripe coconut falls to the ground and remains there. The double coconut palm also grows in.

Reduced radiation rate as a result of failure to speciate is commonly interpreted to result in "evolutionary dead-ends" – lineages that have low adaptation potential and are thought likely to become extinct before they can diversify [23, 24].
