BIOLOGY MYSTERIES

Added on: 22nd Dec 2015

 

BUTTERFLY MIGRATION

Viceroy Butterfly

How do Monarch Butterfly descendants all over Canada and the

United States and eventually, after migrating for several generations,

manage to return to a few relatively small overwintering spots?

No concrete answers have been given to this amazing phenomenon.

 

 

THE LORICIFERA MYSTERY

The Loricifera Mystery

There are at least one hundred species of this phylum that are yet

to be described, and none of them are known to be present

in the fossil record.

 

 

THE PARADOX OF THE PLANKTON

Plankton

In aquatic biology, the paradox of the plankton describes a situation

in which a limited range of resources supports an unexpectedly

wide array of plankton species, apparently flouting the competitive

exclusion principle that holds that when two species compete for the

same resource one will be driven to extinction.

 

 

EBOLA'S ORIGIN AND PLACE OF HIDING

Ebola Virus

We have learned much about the Ebola virus recently to the point

that we have even successfully treated monkeys for it. Nevertheless,

in spite of our strides against the virus, we’re still uncertain as to the

virus’ origin or even where the virus hides between human outbreaks.

 

 

PERCEPTION

Perception

We perceive things every day, but the act of perception is still a relative

mystery. We still don’t fully understand how the brain transforms

sensory information into coherent precepts. We don’t even know the

rules by which perception is organized or how the senses

are even integrated.

 

 

ALKALOIDS

Alkaloids

A group of naturally occurring chemical compounds that are

composed of mostly basic nitrogen atoms, Alkaloids are produced

by a large variety of organisms including bacteria, fungi, plants and

animals. However, their function is not entirely understood and the

scientific community is still searching for answers.

 

 

ADAPTATION

adaptation

At present there is no theoretical model for how adaptation occurs

that is close to being complete. Mathematical models of evolution

describe how the process of natural selection influences the frequency

of already existing gene variants based on their relative fitness

(survival of the fittest). Only a small amount of theory treats the problem

of modelling the generation of new variants through mutation, in

terms of either fitness or phenotypic form.

 

 

HOMING (IN BIOLOGY)

Homing (in biology)

Homing is the inherent ability of an animal to navigate toward an

original location through unfamiliar areas. This location may be either

a home territory or a breeding spot. Even though we are kind of familiar

with the phenomenon of homing, a satisfactory explanation for the

neurobiological mechanisms that cause it has yet to be found.

 

 

HAMMERHEAD SHARK’S STRUCTURE

Hammerhead Shark

The hammerhead shark is known for its distinctive head shape.

However, the reason for this shark’s unusual shape is still not fully

understood. Some have theorized that the hammerhead evolved in order

to increase its electro sensory area, another hypothesis involves better

sight, and yet another hypothesis is the improvement of movement

through the waters.
