Sperm speed gene improves reproduction

Sperm speed gene improves reproduction

Posted Tue, 18 Oct 2016 13:43:26 GMT by Paul Robinson

Could humans benefit from a gene that speeds up the sperm as it swims? In a deer mouse, it works wonders for up to 14 litters per year and 9 offspring per litter! You do the math.

Dolphin worlds are no longer circus-like recreation for humans, but one oceanic species has found it possible to settle down in a relatively restricted habitat. Here is the story of their novel world, with I’m sure, more evolutionary possibilities to come.

It’s likely that these advanced vertebrates evolved extreme matrotrophy only once, but when we compare that habit with many other advanced features, it seems skinks come out top in adaptations for advanced life styles.

We regard the most impressive living things as large animals, such as extinct giants, but to consider the life and influence of great trees or the efficiency of a spectacular army ant raid, killing everything in its path, can’t be disregarded. Maybe we have to have seen these species, or be taught about those that are extinct, to be able to appreciate how significant they have been Just hope they survive long enough for us to be able to see at least some natural wonders like these.

We do need to study other organisms in order to improve our understanding of not only nature, but chemistry, sociability and simple organisation. You would think that a colonising ant would have little to show, but the way in which individuals are empowered, despite that despotic Black Queen, are very revealing !

So much intriguing information is becoming available about our genetic links with the primates, but there is competition from those species who can signal to each other in devious ways, or even tell us a thing or two, checking us out and giving us an idea of what and how they think.

How do we rule this planet? Mostly inadvertently, it seems. The numbers of extinctions are only matched by the displaced species which have become greater in number as they struggle to establish in new niches and habitats, including the pathogens, the unwanted and the invasive.

How can we design experiments to test just how bright animals can be in relation to their own environment and even our own when we consider species that have associated with us and our strange contraptions throughout our short history of technology. The results of investigations tell us something much more than just how cognitive some species are compared to others. This great yet simple work tells us how the ecosystem works in real time.

There is only one animal that has occupied every habitat on land, using simple technologies that have been beyond other species. Here is the first sign of an almost complete history of how the continents were conquered. Unfortunately, it was not only the plants and animals that were dominated, but the ethnic cleansing of other humans that is portrayed in vivid DNA memories.

How can we replace the beautiful Panamanian golden frog. Well, we can breed them in zoos or laboratories. Or go out and find a new golden species to conserve. Take your pick.

We have a record for being obsessed with camouflage in the sea or on land. The incredible lengths that species will go to (evolve) in order to resemble an object that is either dangerous or inedible. The name is mimicry (Batesian or otherwise) and the game here is masquerade.

Teaching is the Oldest Profession.

Posted Tue, 09 Feb 2016 10:47:50 GMT by JW Dowey

How do we evaluate modern humans in their approach to high fidelity learning. We are barely adequate in evaluating teaching, so maybe it is about time we looked more closely at how children really learn. The so-called professionals, from areas that are barely concerned, have failed to agree for generations, even on defining true teaching, instruction, coaching or mentoring properly. That leaves the field wide open for novel or ingenuous suggestions about early (or even late) learning and the teaching that successfully provides it.

The distribution of animals and plants can be absolutely fascinating. While fossils may not interest everybody, the mammals that occupy our earth currently give us a wealth of information. This concerns climate and geological change, as their ancestors, and those who didn’t make it, show us the details of the climate changes that concern us very deeply at this moment in time.
