Domestication is
an evolutionary process by which animals are artificially selected and undergo huge phenotypic behavioral and physiological alterations
(Trut et al., 2009). These transformations occurred at the same time in several regions with a tremendous impact on human societies (Neolithization) (Vigne, 2011).
Is domestication an adaptation?
We discuss the successes, advantages, and challenges of each, but we conclude that bottom-up approaches to understanding domestication as an
adaptive process
hold greater promise both for the study of adaptation and as a means to identify genes that contribute to agronomically important traits.
Is domesticating animals natural selection?
Biologist Charles Darwin called this process evolution by natural selection.
Domestic animals also evolve, but people do the selecting
. Humans seek out qualities like tameness, and help animals with those traits survive and bear young. Darwin called this evolution by artificial selection.
What is domestication in history?
Domestication is
the process of adapting wild plants and animals for human use
. Domestic species are raised for food, work, clothing, medicine, and many other uses. Domesticated plants and animals must be raised and cared for by humans. Domesticated species are not wild.
Is evolution of domestication driven by tameness?
Domesticated species have evolved similar phenotypes
. It has been suggested that this is driven by tameness. … After five generations, they showed several domesticated traits.
Are cats man made?
In a new comprehensive study of the spread of domesticated cats, DNA analysis suggests that cats
lived for thousands of years alongside humans before they were domesticated
. … Two major cat lineages contributed to the domestic feline we know today, they report in a study published Monday in Nature Ecology & Evolution.
What is the difference between domestication and natural selection?
Unlike speciation (natural selection),
domestication leads to a transformation of a species A
(Fig. 2) into an anthropogenic-driven entity, which is still part of that species A (A→A).
Do humans show signs of domestication?
A new study—citing genetic evidence from a disorder that in some ways mirrors elements of domestication—suggests modern humans
domesticated themselves
after they split from their extinct relatives, Neanderthals and Denisovans, approximately 600,000 years ago.

What is an example of domestication?

cattle in Africa, goats in the Middle East, and llamas in South America
.
Who is smarter cat or dog?
However, various studies have concluded that,
overall, cats are not smarter than dogs
. One study often cited is that of neurologist Suzana Herculano-Houzel, who has spent nearly 15 years analyzing cognitive function in humans and animals.
What big cat are house cats most like?
The Siberian tiger
, also known as Panthera tigris altaica. The biggest and perhaps most fearsome of the world’s big cats, the tiger shares 95.6 percent of its DNA with humans’ cute and furry companions, domestic cats.
Do cats fall in love?

. They’re just sometimes a little more subtle about it than dogs. … From slow blinks to purrs, kneading, and following you from room to room, cats show love in many unique and wonderful ways.
Is taming and domestication the same thing?
Taming is
conditioned behavioral modification of an individual
; domestication is permanent genetic modification of a bred lineage that leads to, among other things, a heritable predisposition toward human association.
What is an example of struggle for existence?
These included “
dependence of one being on another
,” animals that “struggle with each other” over limited food resources, plants that “struggle for life against the drought” and that “struggle with other fruit-bearing plants, in order to tempt birds to devour and thus disseminate its seeds.”
Is natural selection genetic?
Natural selection can
produce genetic variation among demes
within a metapopulation if different selective pressures prevail in different demes.
